Test Catalog

Reflex Tests
Lists tests that may or may not be performed, at an additional charge, depending on the result and interpretation of the initial tests.

Test Id Reporting Name Available Separately Always Performed
FSGCU Specific Gravity Confirmation, U No No

Testing Algorithm
Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

If Creatinine result is less than 300 or greater than 3000, Specific Gravity Confirmation, Urine (FSGCU) will be performed, if appropriate, at no additional charge.

Method Name
A short description of the method used to perform the test

Colorimetry (C)

High Performance Liquid Chromatography/Tandem Mass Spectrometry (LS-MS/MS)

Refractometer (REF), if appropriate

NY State Available
Indicates the status of NY State approval and if the test is orderable for NY State clients.

Yes

Reporting Name
Lists a shorter or abbreviated version of the Published Name for a test

Thiosulfate, Urine

Aliases

Thiosulfate, Urine

Testing Algorithm
Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

If Creatinine result is less than 300 or greater than 3000, Specific Gravity Confirmation, Urine (FSGCU) will be performed, if appropriate, at no additional charge.

Specimen Type
Describes the specimen type validated for testing

Urine

Specimen Required
Defines the optimal specimen required to perform the test and the preferred volume to complete testing

***Must submit one specimen per order. Specimens cannot be shared between multiple orders.***

Specimen Type: Urine

Container/Tube: Plastic preservative-free urine container

Specimen Volume: 4 mL

Collection Instructions: Collect 4 mL random urine without preservative. Send specimen refrigerated in a plastic (preservative-free) urine container.

Specimen Minimum Volume
Defines the amount of sample necessary to provide a clinically relevant result as determined by the testing laboratory. The minimum volume is sufficient for one attempt at testing.

1.6 mL

Reject Due To
Identifies specimen types and conditions that may cause the specimen to be rejected

Specimen Stability Information
Provides a description of the temperatures required to transport a specimen to the performing laboratory, alternate acceptable temperatures are also included

Specimen Type Temperature Time Special Container
Urine Refrigerated (preferred) 30 days
Frozen 14 days

Testing Algorithm
Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

If Creatinine result is less than 300 or greater than 3000, Specific Gravity Confirmation, Urine (FSGCU) will be performed, if appropriate, at no additional charge.

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.

PDF Report
Indicates whether the report includes an additional document with charts, images or other enriched information

No

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.

Monday through Sunday

Report Available
The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.

9 to 16 days

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

2 weeks

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

NMS Labs

Test Classification
Provides information regarding the medical device classification for laboratory test kits and reagents. Tests may be classified as cleared or approved by the US Food and Drug Administration (FDA) and used per manufacturer instructions, or as products that do not undergo full FDA review and approval, and are then labeled as an Analyte Specific Reagent (ASR) product.

This test was developed and its performance characteristics determined by NMS Labs. It has not been cleared or approved by the U.S. Food and Drug Administration.

CPT Code Information
Provides guidance in determining the appropriate Current Procedural Terminology (CPT) code(s) information for each test or profile. The listed CPT codes reflect Mayo Clinic Laboratories interpretation of CPT coding requirements. It is the responsibility of each laboratory to determine correct CPT codes to use for billing.

CPT codes are provided by the performing laboratory.
