Procainamide - ANSWER-NAPA
loose clusters of small spherical microconidia, positive urease - ANSWER-
Trichophyton mentagrophytes
BHCG tumor marker - ANSWER-chorocarcinoma
5HIAA - ANSWER-carcinoid tumors
Proteus vulgaris vs P. mirabilis indole test - ANSWER-P. vulgaris is indole pos. P.
mirabilis is indole neg
Hydatid cyst fluid - ANSWER-used to neutralize Anti-P1 antibody
Antacid overdose - ANSWER-Check pH
,Prolonged PT, PTT, and thrombin after collecting from catheter - ANSWER-heparin
contamination
mixing study that was performed with a prolonged PTT that couldn't be corrected
- ANSWER-DRVVT (Dilute Russell Viper Venom Test)
two pt's ran in duplicate (PT and PTT). The PTT seemed to always be prolonged
but PT looked ok - ANSWER-check the CaCl/phospholipid reagent delivery
Patient is on coumadin therapy, what will be affected - ANSWER-Decreased
protein C
Lot's of stomatocytes - ANSWER-Liver disease
Burr cells - ANSWER-Uremia
Picture of target cells with hemoglobin C crystals. The white count was high on
instrument 1, so a second instrument was used with a stronger lysing agent, and
the white count was corrected - ANSWER-anti-lysing target cells are what
increased the white count? Erythrocytes containing hemoglobin C do not lyse
normally (sickle cell diseases)
A sodium citrate tube was drawn for a HCT on a pt but the hematocrit was
abnormal - ANSWER-recollect with decreased anticoagulant. high hct (>55%)
causes low plasma so you need less anticoagulant

found that the HGB didn't meet the rule of 3 because it was too high - ANSWER-
check for lipemia (elevates HGB)

ANSWER-Prussian blue for howell jolly bodies made of iron. Prussian blue stain,
which is not taken up by reticulocytes, is helpful in differentiating the two.
what is composed of DNA? - ANSWER-howell jolly bodies
what falsely increases ESR - ANSWER-vibration, tilting of tube, higher temps, >1 hr
test time, improper mixing of blood, improper dilution
factors decreasing ESR - ANSWER-Polycythemia, Microcytosis (Hb C), Sickle cells,
spherocytes, Anti-inflammatory medications, Hypogammaglobulinemia,
Hypofibrinogenemia (DIC), High WBC count, Hyperviscosity
Factors increasing ESR - ANSWER-Anemia, Macrocytosis, Female gender, Age >50
years, Obesity, Pregnancy, Hypercholesterolemia, cancer, multiple myeloma,
rouleaux, infections, inflammation
what falsely decreases ESR - ANSWER-low blood/ room temps, air bubbles, tests
<1 hr, improper mixing of blood, improper dilution
lactic acid collection - ANSWER-separate from serum and put on ice
