Red/Yellow Speckled Top Urine Tube (Ethylparaben, sodium propionate and chlorhexidine preservative); 8 mL urine

Urine Collection Guide

Storage and Transport

Specimen should be examined within 2 hours of collection or promptly refrigerated at 2 – 8° C.

Special Instructions

Random specimens are usually considered adequate for most analysis. If bacterial evaluation is also desired, a midstream clean catch should be obtained.

Causes for Rejection

Improper labeling; improper storage or transport; leaking container; insufficient quantity

Reference Range

Specific gravity 1.001 – 1.030; pH 4.6 – 8; Protein, Glucose, Ketones, Bilirubin, Leukocytes, Blood and Nitrites negative; Urobilinogen 0.2 – 1.0 Ehrlich units/dL. WBC None Seen/HPF; RBC None Seen/HPF; Bacteria None Seen/HPF; Renal tubular and transitional epithelial cells 0 – 5 /HPF; Squamous Epithelial Cells 0-2/HPF; 0 – 3 hyaline casts/LPF;
