WBC casts and increased numbers of WBC’s in urine is indicative of:

An example of an amorphic gene in the blood group systems is:

A wound specimen was inoculated onto two sheep blood agar plates (SBAP): one plate was incubated aerobically and the other anaerobically.  After 48 hours incubation, colonies which were gram stained as gram-positive rods and were catalase negative were observed on both the aerobic sheep blood agar plate (1+ growth), and the anaerobic sheep blood agar plate (4+ growth).  The technologist subcultured the colony from the anaerobic plate to sheep blood agar incubated aerobically, a sheep blood agar plate incubated in a candle jar and a sheep blood agar plate incubated anaerobically.  Again growth of the same colony was observed on the aerobic SBAP (1+ growth), SBAP in the candle jar growth (2+ growth) and anaerobic SBAP (4+ growth).  At this point which of the following organisms is most likely?

Insufficient washing when performing an antiglobulin test will result in:  

Trichrome stains would be most appropriate for detecting which of the following organisms from clinical specimens?

A urine specimen might be examined for which of the following parasites? Schistosoma haematobium Schistosoma japonicum Trichomonas vaginalis Trichuris trichiura

In the Wroblewski method, total LD activity by kinetic methods is measured by the following reaction:                                         LD            pyruvate + NADH2

The antigen that is negative when the secretor gene is present:

Situation:  The findings of a first morning urine from a patient with 152 mg/dl blood glucose were:  pale, hazy; specific gravity, 1.030; pH, 6.0; glucose strongly positive; acetone and albumin – negative; microscopic; rare red blood cells, 0-3 WBC, yeast cells.  These findings might reasonably suggest a diagnosis of:

Patients with severe hemolytic anemia usually have which of the following peripheral blood changes?
