Test ID HIPA Hippuric Acid, Urine

Method Name

Colorimetry (C)

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

Reporting Name

Hippuric Acid, U

Specimen Type

Urine


Specimen Required


***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: 2 mL

Collection Instructions:

1. Collect 2 mL random urine specimen in a plastic preservative-free urine container at end of shift.

2. Send refrigerate.

NOTE: The acidification of the urine with 1.0 mL acetic acid per 100 mL urine will prolong the stability of the analyte.


Specimen Minimum Volume

1.1 mL

Reference Values

Reporting limit determined each analysis

 

Creatinine:

U.S. Population (10th-90th percentiles, median)

All participants: 335-2370 mg/L, median: 1180 (n=22,245)

Males: 495-2540 mg/L, median: 1370 (n=10,610)

Females: 273-2170 mg/L, median 994 (n=11,635)

 

Hippuric Acid:

Normal for unexposed populations is generally less than 1.6 g/L.

 

Hippuric Acid (Creatinine corrected):

Normal for unexposed populations is generally less than 1.5 g/g creatinine.
