Procedure #1 detected 50/100 true positives & 100/100 true negatives. Procedure #2 detected 80/100 true positives and 70/100 true negatives. - Procedure 2 is more sensitive (refers to % of true positives that are accurately identified as positives). Specificity refers to # of true negatives identified as negative. TP/TP+FN= - Sensitivity TN/TN+FP= - Specificity What might the following indicate in urine: RBCs, WBCs, nitrite, and bacteria? - Pyelonephritis (UTI); WBCs and nitrites in uri...

B. Potassium ferricyanide and potassium cyanide B. The standard assay for hemoglobin utilizes potassium ferricyanide. This solution, formerly called Drabkin's reagent, is now called cyanmethemoglobin (HiCN) reagent. The ferricyanide oxidizes hemoglobin iron from ferrous (Fe2+) to ferric (Fe3+), and the potassium cyanide stabilizes the pigment as cyanmethemoglobin for spectrophotometric measurement - correct answer What combination of reagents is used to measure hemoglobin? A. Hydrochloric...

Insufficient centrifugation will result in: a. a false increase in haematocrit (Hct) value b. a false decrease in Hct value c. No effect on Hct value d. all of these options, dependent on the patient - a. insufficient centrifugation does not pack down the red blood cells; therefore, the Hct, which is the volume of packed cells, will increase variation in red cell size observed on the peripheral smear is described as: a. anisocytosis b. hypochromia c. poikilocytosis d. pleocytosis - a. a mature ...
