Protein, Total, Urine : 0020479

Mnemonic: UTP

Methodology: Spectrophotometry
Performed: Sun-Sat
Reported: Within 24 hours
Specimen Required: Collect:  24-hour urine (no additive). Also acceptable: random urine. Specimen must be refrigerated during collection.

Storage/Transport Temperature:  4 mL aliquot from a well-mixed 24-hour collection at 2-8°C. (Min: 1 mL)  Submit specimen in an ARUP Standard Transport Tube.

Remarks:  Record total volume and collection time interval on transport tube and test request form.

Unacceptable Conditions:  Specimens collected in acid (such as those previously preserved with HCl).

Stability (collection to initiation of testing):  Ambient: 8 hours; Refrigerated: 3 days; Frozen: 1 month
