How to Read a Toxicology Report Understanding what the results mean will depend on a couple of factors. These include the number of panels in a drug test (5-panel, 12-panel, etc.) and whether you opted for a hair or urine test. With urine tests, you can get results instantly.
Medical examiner office personnel can also conduct toxicology drug testing related to an autopsy. Toxicology drug testing laboratories where the analyses are carried out are accredited by such organizations as the College of American Pathologists or state health departments or other organizations, to ensure uniform quality standards.
Samples of the stomach contents and bile, a digestive juice secreted by the liver, are also collected routinely. The tissue and fluid collection is typically done by a pathologist or morgue assistant, Robin says, and the process usually takes just 15 or 20 minutes. Next, the specimens are turned over to a toxicology expert for testing.
''The toxicology report showed the presence of cocaine at a level sufficient to cause death," she says. And the belligerent behavior was another clue. But not every toxicology report is so clear-cut, Robin says.
What is a Toxicology Report? A toxicology screen, is used to gauge the amount of drugs and alcohol that are present in your system. They’re used to indicate whether you have substance abuse issues, or just to detect the use of illegal drugs. The types of drugs detected will depend on the type of drug test.
There are several ways that a toxicology screen is administered. The most common ways are by taking a urine or hair sample.
If there is a negative result, you’ll get the report quickly. However, a positive result will require confirmation. The sample will be retested for specific drugs followed by a confirmation of the cutoff levels.
A hair drug screen will tell you whether or not drugs or alcohol were taken in the past 90 days. This can show an extended pattern of behavior and drug use. Similar to urine tests, the initial tests will be positive or negative. If there is a negative result, you’ll get the report quickly.
It helps to understand the process of drug screens. They typically go through three stages. The first is the initial screen to detect the presence of drugs.
In some cases, a drug screen is ordered by the courts to ensure sobriety. No matter what your reason is for getting a drug screen, it’s important to interpret and understand the results. This guide explains what a toxicology report is, as well as how to read and understand toxicology reports so you’re not left in the dark.
A colored line that appears on the control and test lines is a negative result. If a line does not appear on the test line, that indicates a positive result. Positive results are more common than you think. About 4% of results test positive, and that number has grown over the last few years. There is an option to get a more in-depth test done ...
A dose is a measured quantity typically of a medicine or a nutrient. Doses are measured in units, these units can be pre-measured pills, or they can be liquid medications measured in milliliters, teaspoons, and/or tablespoons.
Dosages of medication and/or nutrients are developed based on people’s body weight. Manufacturers will look at several variables, including a typical person’s body weight, the amount entering the body (absorption capacity), the movement of the drug throughout the body (distribution), the breakdown of the medication throughout the body (metabolism), ...
The dose-rate is the frequency someone takes a dose of a medication or nutrient. For example, if you are taking a medication for a bacterial infection, you may be required to take one dose of the medication two times a day, approximately 12 hours between each dose for five days.
It’s important to take all medications as advised by a credentialed medical professional because they will know and make recommendations for your specific medical situation.
If a doctor prescribed it, call the doctor or pharmacist and ask how to proceed safely. If it’s an over the counter medication, contact your doctor, pharmacist, or the poison control center for next steps.
If you suspect you or someone you know has taken a life-threatening overdose of medication, contact emergency services immediately. If it’s a less serious matter, you can contact your local pharmacist or your poison control center .
Yes, it’s essential to take all prescribed medications as recommended unless you’ve contacted your doctor and/or pharmacist in advance.
The final toxicology report may incorporate other information, such as field evidence at the scene of the crime, or the possibility of fatal drug interactions, to determine the cause of death. Finally, before the results of the toxicology test and cause of death can be made public, the family must be notified. 1.
However, in reality, while an autopsy is usually completed within a day or two after a death, the final results of the toxicology report may take four to six weeks or longer . Many factors play into the length of time needed to gather forensic toxicology test results, including: the need for confirmatory testing.
Forensic toxicology testing, also known as postmortum toxicology testing, is conducted by a laboratory for medical and legal purposes, which may include death and criminal investigations. The results, which are often considered as evidence, may be subject to use in a court of law.
Death investigations are conducted by law enforcement and health officials at the scene to gather any forensic evidence which may include prescription drugs, illicit substances, or over-the-counter medications, and any available information about the prescribers.
Many drugs stay in the system from 2 to 4 days, although chronic use of marijuana can stay in the system for weeks after the last use. Drugs with a long half-life, such as the benzodiazepine diazepam, may also stay in the system for a prolonged period of time.
Negative results are usually received within 24 hours, however, a positive screen will require further testing that may take a few days up to one week.
Drug testing is common for many U.S. employers, to lessen the impact from drug abuse in the workplace. 2 The National Institutes of Drug Abuse (NIDA) reports that drug use costs the US economy more than $700 billion annually in increased health care costs, crime, and lost productivity. 3.
Being provided with a toxicology report allows a clearer understanding of the results, which can assist, along with other evidence, toward the overall outcome of a case. By having results alone with no expert interpretation, can cause misinterpretation of the evidence and consequently a potential miscarriage of justice.
Depending on the types of test and export statement needed, we advise that a toxicology report could take approximately between 24 hours and up to 3 weeks to be completed, though a few days is more likely. The reason the test is not faster could be that the lab has a backlog of tests that they need to do - this problem is amplified in metropolitan areas, where the number of testing facilities per capita is lower.
Toxicology , the study of the effects of drugs, chemicals, poisons, and other substances on living organisms, is a very interesting field that can have major implications in the legal world. Thanks to the expert work of toxicologists and their toxicology reports, the samples of hair, urine, blood, and other bodily fluids/matrices, can show whether someone has used or is using drugs, legally or illegally, or has been exposed to certain chemicals or toxins.
Patient data: Name, date of birth, pre-existing medical conditions, medical prescriptions, previous drug and/or alcohol history, and any products that can affect the results, such as hair chemical treatments.
Explanation of the findings: A detailed interpretation of results. The summary will interpret positive results and provide a conclusion based on the likelihood probability for how the positive result is present. For example, in regards to cannabis, it could suggest whether the results are more likely due to external/passive exposure to cannabis or from direct inhalation.

In many cases, yes, the toxicology report is a public record, however, in some cases, privacy laws intervene and keep the report as a private document - it all depends on the circumstances. In the case of a deceased individual, their toxicology report will form part of the coroner’s autopsy report, which may be obtained from the coroner’s office by request. We adhere to the GDPR guidelines; DNA Legal is committed to ensuring that your privacy is protected.
The final toxicology report, he says, draws not only from multiple test results and confirmation of the results, but also on the clinical experience of the toxicologists and pathologists involved in the investigation, as well as field work. Here is what toxicology tests include, why they take so long, and why they can be tricky.
Next, the specimens are turned over to a toxicology expert for testing. Testing is typically done by medical technologists or chemists, such as forensic chemists with doctoral training who are certified by The American Board of Clinical Chemistry or the American Board of Forensic Toxicology, according to the College of American Pathologists.
The toxicology testing performed after a person's death is known as forensic toxicology testing or postmortem drug testing.
The basic toxicology screen typically uses an immunoassay, Robin says. This type of test looks for drugs in the blood using specific antibodies that detect various classes of drugs.
Specimens taken for forensic toxicology testing routinely include, in addition to blood and urine, tissue samples from the liver, brain, kidney, and vitreous humor (the clear ''jelly" found in the eyeball chamber), according to information from the College of American Pathologists.
In real life, toxicology test results take much longer. "Some of the tests take days, weeks, months ," says Alan Hall, MD, a board-certified toxicologist and consultant in Laramie, Wyo.

Other types of toxicology testing include workplace drug testing, which also screens for drugs of abuse, and athletic drug testing in sport programs, which detect banned substances or drugs that enhance performance.
The Toxicology Module can detect drugs and metabolites of drugs. The lab results are easy to understand. The module displays a consistent or inconsistent outcome based on a database within the system.
After doctors prescribe medications, administering the correct dosage is left up to the patient. To make sure drugs are being used correctly, doctors need to regularly test their patients.
Avalon LIS can automatically tell the doctor if results are consistent with the prescribed drugs the patient is supposed to be taking.
The 2 categories of commonly used toxicology tests are antibody-based immunoassays (usually an enzyme-mediated immunoassay [EIA]) and specific drug identification tests (such as gas chromatography–mass spectroscopy [GC-MS]). EIA tests utilize antibodies to specific opiates that bind to that opiate when present in a sample to produce a measurable reaction. These tests have the advantages of decreased cost and excellent sensitivity2and are readily available in both hospitals and clinics. However, while the tests are quick and relatively easy to use, their specificity is limited by cross-reactivity and, consequently, can result in false-positive results.
Drug screening can be conducted on urine, blood, hair, saliva, sweat, and nails. However, urine is the most commonly used specimen in drug testing across clinical sites given its ease of collection and rapid analysis. In addition, the concentration of drug metabolites in the urine tends to be higher than those of serum samples.1
Two common potential causes for false-negative opiate tests are using the wrong test for a specific opiate and having an insufficient concentration of an opiate in the sample. Clinicians may minimize such errors by keeping in mind the specific opiates being tested for. Most of the above-mentioned semisynthetic and synthetic opiates have their own standardized EIAs with excellent sensitivities,14some of which may be a part of a hospital’s standard toxicology screen. All physicians should be aware of which EIA tests are part of their hospital’s standard toxicology screen and the potential need to specifically request EIA tests for synthetic opiates. Concentration of a substrate in a sample is dependent upon a drug’s individualized absorption and metabolism rates as well as on the drug’s pharmacokinetics. Toxicology tests are designed with cutoff concentrations in mind; these cutoffs represent the lowest possible concentration that will produce a positive test result. These tests are calibrated to detect opiates taken within 1 to 3 days in the majority of individuals15; however, individual variation that is based on metabolic genotype (eg, ultrafast metabolizers) should be considered.
The second category of tests allows for specific drug identification using gas chromatography (GC) (used to separate different molecules in a sample) followed by mass spectroscopy (MS) (wherein spectrographic patterns are compared to a standard to identify the separated molecule). GC-MS is considered the gold standard for confirmatory testing; it allows for quantification and identification of drugs and their metabolites, with sensitivities and specificities of 99%.3While GC-MS is highly accurate, it is time-consuming and requires a higher level of expertise to perform than immunoassays. For these reasons, GC-MS is more expensive and less available and is usually performed only after a positive EIA test result has been obtained.
All of these concerns must be balanced against the risks (eg, slipping into dangerous waters with the patient and partaking in an uneven sense of responsibility in the therapeutic relationship) of the overly-trusting clinician. Surreptitious use of medications or illicit drugs is an example of a “real-life” clinical situation that can place the patient at risk of oversedation or untoward drug-drug interactions. Moreover, abuses of the medical system are a valid concern for physicians to whom society is increasingly looking to act as gatekeepers for progressively strained medical resources. Finally, when confrontation is assiduously avoided by the clinician it can contribute to an imbalance in the therapeutic relationship (the patient expects care without reliably demonstrating healthy decision-making). This imbalance may ultimately disempower the patient and limit his or her sense of responsibility (regarding their health care) and can contribute to powerlessness on the part of the clinician.21,22
Physicians often perceive that their skepticism (and ordering of drug testing) is necessary to establish diagnostic certainty; it allows them to go beyond reliance on subjective reporting that can be embellished for secondary gain or be colored by a patient’s personality.16Yet , the inherent danger of doubting a patient’s self-reported history is the creation of diagnostic inaccuracy (the very thing that the physician is trying to avoid). Physicians tend to have more difficulty believing a patient with unusual symptoms or an illness course that fails to fit a well-established pattern; such distrust may lead to meaningful symptoms being discounted, delayed, dismissed (as trivial), incorrectly diagnosed, and/or inadequately treated.16
A physician’s trust in a patient may enhance the patient’s trust in the physician, while the lack of physician trust is perceived negatively by many patients and may, in turn, adversely affect a patient’s behavior. 19,20This lack of trust could be manifest by nonadherence with treatment recommendations, by missing appointments, or by an unwillingness to openly and accurately describe symptoms; each of these behaviors perpetuates and erodes the doctor-patient alliance.20Moreover, future treatments can be jeopardized if a physician’s skepticism is documented in the medical record (allowing it to be easily accessed and referenced by others).
Toxicology tests can be conducted on living and deceased persons and go further by testing for the presence of prescription drugs, commonly abused substances like alcohol, cocaine or marijuana, or a particular poison in the body. The findings are disclosed in a toxicology report and indicate whether any drugs or poisons in the body led to the person's illness or death. For example, if the autopsy reveals damage to organs and tissue consistent with death by poisoning, a toxicology panel will confirm that cause of death by showing whether the decedent had poison in his system.
Autopsy and toxicology reports are routinely used as evidence in lawsuits and in criminal cases. For example, if a family is struck and killed by a drunk driver on their way back from Disneyland, the attorney prosecuting the drunk driver may use each family member's autopsy report to show that they died from injuries sustained in the car accident and not some other unrelated cause. The prosecutor also may use the defendant's toxicology report to show his blood alcohol level was over the legal limit at the time of the accident.
Reports Help Explain Cause of Death. During an autopsy, the physician looks for evidence of disease, injury or other abnormality by investigating both the inside and outside of the body, including the brain, tissues and organs.
