ASCP: Study Questions
1. Procedure #1 detected 50/100 true positives and 100/100 true negatives.
Procedure #2 detected 80/100 true positives and 70/100 true negatives.
b. procedure 2 is more sensitive
2. TP/TP+FN = ?
b. specificity
3. What might the following indicate? urine: RBCs, WBCs, nitrite, bacteria
a. pyelonephritis
4. Why is albumin the first protein to be detected in tests for renal failure?
b. its molecular size is smallest
5. Cortisol excess will result in _____
a. hypernatremia
c. elevated glucose levels in blood
6. What is the reason for this discrepancy or What would you do to resolve this discrepancy? Patient cells Patient serum anti-A anti-B A cells B cells 3+ 3+ 1+ 0 This is a reverse group discrepancy, most likely to a subgroup of A. comment? A2 subgroup is most commonly seen in patients that are AB, about 25% of them make anti-A1. So this is most likely due to A2B patient making anti-A1
Resolve by incubating at room temp 15 min
7. This spiral-form organism is seen in urine and cultured on Fletcher’s media
b. Leptospira
8. Organism that gives off a bleach-like odor in culture?
b. Eikenella
9. Presence of rheumatoid factor in blood may result in false positives for what test?
a. VDRL
10. Disease associated with the following results? Elevated TSH; Elevated T3; Elevated free T4
b. hyperthyroidism
Pituitary tumor

a. Calcium
12. Mucoid, pink colonies on plate; produces gas; indole (+). On TSI tube you see yellow on the slant and yellow in the deep. What organism is this?
