Litholink testing provides physicians with high quality results and helps physicians prevent kidney stones from reoccurring. Physicians can order 24-hour urine collection(s) and have a kit shipped to a patient's home.
"Normal" 24-hour urinary citrate is about 320 mg. "Optimal" 24-hour urinary citrate for calcium stone formers is about 320 mg per 1,000 ml urine, typically totaling about 640 mg or more and assuming an optimal daily 2,000 ml of urine.
The normal level of urine oxalate excretion is less than 45 milligrams per day (mg/day). A higher level of urine oxalate may mean you are at risk of developing kidney stones. Risk of stone formation seems to increase even at levels above 25 mg/day, which is considered a normal level.
Normal Results The normal range for 24-hour urine volume is 800 to 2,000 milliliters per day (with a normal fluid intake of about 2 liters per day). The examples above are common measurements for results of these tests.
Test results from a 24-hour urine collection are typically available the same day. The test results will be sent to your doctor, who will share them with you.
Low urinary citrate excretion is a known risk factor for the development of kidney stones. 1. Hypocitraturia, generally defined as urinary citrate excretion less than 320 mg (1.67 mmol) per day for adults,2 is a common metabolic abnormality in stone formers, occurring in 20% to 60%.
High levels can indicate ammonia toxicity. Chronic loss of these valuable compounds can contribute to loss of organ reserve and disturbances in neurological function. If they are low they can indicate a need for essential amino acids, especially arginine.
Most secondary causes of hypocitraturia decrease urinary citrate by increasing proximal renal tubular reabsorption. Secondary causes of low citrate include dehydration, metabolic acidosis, hypokalemia, thiazide diuretics, carbonic anhydrase inhibitors, magnesium depletion, renal tubular acidosis, and diarrhea.
Calcium oxalate crystals are the most common cause of kidney stones — hard clumps of minerals and other substances that form in the kidneys. These crystals are made from oxalate — a substance found in foods like green, leafy vegetables — combined with calcium.
They're colorless and can be found in healthy urine. Calcium oxalate crystals are heavily associated with kidney stones, which can form when too much oxalate (found in such foods as spinach) is in the system. Kidney stone symptoms include severe groin or abdominal pain, nausea, fever, and difficulty passing urine.
Urinalysis. Urinalysis involves a health care professional testing your urine sample. You will collect a urine sample at a doctor's office or at a lab, and a health care professional will test the sample. Urinalysis can show whether your urine has blood in it and minerals that can form kidney stones.
Dr. Fredric Coe, a leading expert in kidney stone disease, founded Litholink to bring state-of-the-art kidney stone treatment techniques to physicians nationwide.

You can use those numbers to understand how things stand with you. Reading the numbers can help you achieve your best possible chance at stone prevention – which is the only reason all those lab tests were done in the first place.
Stone risk increases with urine calcium excretion above 200 mg/day in men and women – take a look. The calcium risk is at the upper left corner of the graph.
Urine volume is measured in liters (L) or milliliters (ml). A milliliter is 1/1,000 of a liter, so there are 1,000 ml in a liter. One liter is 1.06 quarts. The laboratory measures the total volume of urine if you send or bring it. Often you will read the volume yourself, off of a collection container.
Time. Because excretions of stone risk factors are in amount per 24 hours , we need the time of the collection. You provide the beginning and end times for the collection, in minutes and hours, and the laboratory corrects all excretion values to amounts in 24 hours.
If the volume is 1.5 liters, the volume ‘corrected’ to 24 hours is 1.5 liters x 24 /22 (1.09) or 1.636 liters/24 hours. It is obvious that the less ‘correcting’ the better, because the ‘correction’ assumes that every hour is the same as every other hour, which is not likely.
Acidity or alkalinity are measured in pH – no units. It is a logarithm to the base 10 so a change from 6 to 5 means a 10 fold increase in acidity, from 6 to 7 a ten fold increase in alkalinity.
Stone risk increases with increasing urine oxalate and if the risk ratio is not as high as for calcium risk appears at very low levels of excretion – above 25 mg/day. In general, high urine oxalate comes from high oxalate diets, low calcium diets, or the combination of high oxalate and low calcium together.
