Test ID: CTSA    
Ceramide Trihexoside/Sulfatide Accumulation in Urine Sediment, Urine

Method Description Describes how the test is performed and provides a method-specific reference

One-dimensional thin-layer chromatographic technique is used to indicate the presence or absence of ceramide trihexoside or/and sulfatides. Markers for ceramide trihexoside and sulfatide are run on the same plate as the patient's sample for easy identification.

 

The patient's urinary sediment is extracted to obtain the organic lipids. The extraction is then purified to remove the non-polar lipids. The remaining lipids, a control specimen, a glycosphingolipid standard and markers are separated using thin-layer chromatography. The elevation of ceramide trihexosides or/and sulfatides is qualitatively determined by a side-by-side comparison with standard, control, and markers.(Unpublished Mayo Method)

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

Friday; 9 a.m.

Analytic Time Defines the amount of time it takes the laboratory to setup and perform the test. This is defined in number of days. The shortest interval of time expressed is "same day/1 day," which means the results may be available the same day that the sample is received in the testing laboratory. One day means results are available 1 day after the sample is received in the laboratory.

7 days

Maximum Laboratory Time Defines the maximum time from specimen receipt at Mayo Medical Laboratories until the release of the test result

14 days

Specimen Retention Time Outlines the length of time after testing that a specimen is kept in the laboratory before it is discarded

6 days

Performing Laboratory Location The location of the laboratory that performs the test
