Clinical Information

Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test
Chyluria is a medical condition in which chyle is present in the urine. Chyle is a milky substance composed of lymphatic fluid and chylomicrons formed in the small intestine during the digestion of fatty foods. Chyluria is most prevalent in tropical areas where it is caused by parasitic (Wuchereria bancrofti) infections spread by mosquitoes. Parasitic chyluria is so rare as to be nonexistent in the continental United States. Nonparasitic chyluria causes include traumatic lesions, tumors, lymphangioma, pregnancy, and granulomatous infections.
Reference Values
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.

This assay provides information regarding the fat content in urine fluid. Urinary cholesterol and triglyceride values are normally less than 10 mg/dL. High triglyceride levels in urine may indicate chyluria.
Cautions
Discusses conditions that may cause diagnostic confusion, including improper specimen collection and handling, inappropriate test selection, and interfering substances

Ascorbic acid (vitamin C) interferes with the cholesterol determination and, to a lesser degree, the triglyceride concentration. Ascorbic acid falsely decreases the cholesterol and triglyceride results.
Result can be falsely decreased in patients with elevated levels of N-acetyl-p-benzoquinone imine (NAPQI)-a metabolite of acetaminophen, N-acetylcysteine (NAC), and metamizole.

This test involves 2 steps: centrifugation and lipoprotein electrophoresis to detect the visual presence of chylomicrons. The specimen also is analyzed for cholesterol and triglycerides using an enzymatic colorimetric method. The results of the cholesterol and triglycerides and lipoprotein electrophoresis are used together to determine whether the sample is chyluria.(Unpublished Mayo information)

Day(s) Performed
Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.
