What Urinalysis and Other Body Fluids questions test

  • Physical exam: specimen types and handling, color and clarity, specific gravity and osmolality, and changes in unpreserved urine
  • Reagent strips: the reaction behind each pad and its false positives and negatives, and confirmatory tests
  • Microscopic exam: cells, casts, crystals, microorganisms and artifacts, and what each cast type says about the kidney
  • Renal physiology and disease: glomerular and tubular function, glomerulonephritis, nephrotic syndrome, pyelonephritis and metabolic disorders
  • Body fluids: CSF tube order and xanthochromia, transudates and exudates, synovial crystals under polarized light, semen and amniotic fluid tests

How to study it

  • Make a table of each strip pad: principle, false positive, false negative.
  • Pair each cast with the disease it points to, and each crystal with the urine pH it forms in.
  • Learn ASCP’s published urine, CSF and semen reference ranges; the exam does not give them.

Common questions

How many urinalysis questions are on the ASCP exam?

Urinalysis and Other Body Fluids is 5–10% of both exams. Our MLT mock includes 8 questions from this area and our MLS mock 7.

Are body fluid cell counts in this area or hematology?

Both. ASCP’s hematology outline includes cell counts and differentials for blood and body fluids, while the urinalysis and body fluids area covers their physical, chemical and microscopic exam and the disease states.
