Which hematology parameter is MOST useful to distinguish iron deficiency anemia from anemia of chronic disease?
Answer: Serum ferritin
Serum ferritin is low in iron deficiency but normal or elevated in anemia of chronic disease, making it the most discriminating test.
A urine culture grows >100,000 CFU/mL of a single organism with a positive oxidase test and fruity odor. Which organism is MOST likely?
Answer: Pseudomonas aeruginosa
Pseudomonas aeruginosa is oxidase-positive and produces pyocyanin, giving cultures a fruity (grape-like) odor.
In the ABO blood group system, which antibody class is responsible for immediate hemolytic transfusion reactions?
Answer: IgM
IgM anti-A and anti-B are naturally occurring, complement-fixing antibodies that cause severe intravascular hemolysis in ABO incompatibility.
A chemistry analyzer flags a lipemic specimen. Which test result is MOST likely to be artifactually lowered?
Answer: Sodium
Lipemia causes volume displacement, artifactually lowering the measured concentration of electrolytes like sodium (pseudohyponatremia).
Which fungal organism produces germ tubes when incubated in serum at 37°C for 2–3 hours?
Answer: Candida albicans
Candida albicans produces germ tubes (Reynolds-Braude phenomenon) in serum at 37°C, which is a rapid presumptive identification test.
Which coagulation factor deficiency results in a prolonged PTT but normal PT and thrombin time, with NO bleeding tendency?
Answer: Factor XII
Factor XII (Hageman factor) deficiency prolongs PTT but causes no clinical bleeding because it is not essential for in vivo hemostasis.
A body fluid differential shows 95% lymphocytes with no mesothelial cells. This pattern is MOST consistent with:
Answer: Tuberculous pleural effusion
Tuberculous pleural effusions characteristically show lymphocyte predominance with sparse or absent mesothelial cells.
