On chemical examination, a urine specimen tested positive for protein. Also, the Medtech noted the presence of hyaline casts, granular casts, and a number of RBCs on microscopic examination. This is most probably due to:

A urine specimen tested 4+ for protein. On microscopic examination, fatty casts as well as RBCs and renal tubular cells were observed. This could indicate:

A urine specimen is dark orange and turns brown after storage in the refrigerator overnight. The technologist requests a new specimen. The second specimen is bright orange and is tested immediately. Which test result would differ between the two specimens?

A patient’s random urine consistently contains a trace of protein but no casts, cells, or other biochemical abnormality. The first voided morning sample is consistently negative for protein. These findings can be explained by:

A urine sample with a pH of 8.0 and a specific gravity of 1.005 had a small positive blood reaction, but is negative for protein and no RBCs are present in the microscopic examination of urinary sediment. What best explains these findings?

A 5-mL urine specimen is submitted for routine urinalysis and analyzed immediately. The SG of the sample is 1.012 and the pH is 6.5. The dry reagent strip test for blood is a large positive (3+) and the microscopic examination shows 11–20 RBCs per HPF.
