MLS ASCP Exam Questions 2023 With Complete Solution

c antigen is most common in blacks and whites; anti-c would be most common reactive - Correct Answer-Rh antibodies show enhanced reactivity with enzyme pretreated cells. The M and Fya antigens are cleaved from enzyme pretreated cells and therefore there would be no reaction between enzyme pretreated cells and serum containing anti-M or anti-Fya. The incidence of the c antigen is 80% in whites and 96% in blacks. The incidence of the E antigen is 29% in whites and 22% in blacks. Increased reactivity with enzyme pretreated cells and incompatible results with 8 of 10 donor units is most likely due to anti-c. Procainamide - Correct Answer-NAPA loose clusters of small spherical microconidia, positive urease - Correct AnswerTrichophyton mentagrophytes BHCG tumor marker - Correct Answer-chorocarcinoma 5HIAA - Correct Answer-carcinoid tumors Proteus vulgaris vs P. mirabilis indole test - Correct Answer-P. vulgaris is indole pos. P. mirabilis is indole neg Hydatid cyst fluid - Correct Answer-used to neutralize Anti-P1 antibody Antacid overdose - Correct Answer-Check pH Prolonged PT, PTT, and thrombin after collecting from catheter - Correct Answerheparin contamination mixing study that was performed with a prolonged PTT that couldn't be corrected - Correct 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 - Correct Answer-check the CaCl/phospholipid reagent delivery Patient is on coumadin therapy, what will be affected - Correct Answer-Decreased protein C Lot's of stomatocytes - Correct Answer-Liver diseaseBurr cells - Correct 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 - Correct Answer-anti-lysing target cells are what increased the white count? Erythrocytes containing hemoglobin C do not lyse normally (sickle cell diseases)
