What is the glomerular filtration rate for a patient with a serum creatinine of 2 mg/dL, if the urine creatinine was 124 mg/dL and the urine volume was 2.2 L/24 hrs? - ANSWER-95 mL/min One method of calculating a glomerular filtration rate is using creatinine and urine volume to determine creatinine clearance. The equation is as
follows:
Creatinine Clearance = (urine creatinine X urine flow rate) / plasma creatinine; where urine flow rate = volume in mL /24 hours x h/60 min)
In this case = creatinine clearance = 124 X (2200/24 x hour/60) / 2 = 94.7 or 95 ml/min
Estrogen and progesterone markers are most commonly used to provide
prognostic information about: - ANSWER-Breast cancer
The prozone effect ( when performing a screening titer) is most likely to
result in: - ANSWER-Prozone effect (due to antibody excess) will result
in an initial false negative in spite of the large amount of antibody in the serum, followed by a positive result as the specimen is diluted. 1 / 3

The accuracy of an immunoassay is its ability to discriminate between results that are true positives and results that are true negatives. Two parameters of test accuracy are specificity and sensitivity. Which of these statements apply to an immunoassay with high specificity, but low sensitivity? - ANSWER-Accurately identifies the absence of disease and has few false-positives
A test with high specificity accurately detects the absence of disease.The more specific a test is, the fewer false-positive results will occur. A test with high sensitivity accurately identifies the presence of disease.The more sensitive a test, the fewer false-negative results it produces. In the case stated in this question, the immunoassay has high specificity, so it has few false-positives and will accurately detect those individuals who do not have the disease or condition that is being tested for.However, the test has low sensitivity, so it may not identify all individuals who actually have the disease; it may produce many false- negative results.

Distinguishing characteristics of Micrococcus luteus: - ANSWER-
Resistance to furazolidone is one of the key characteristics by which members of the genus Micrococcus (resistant) can be separated from members of the genus Staphylococcus (susceptible). Micrococcus species also are susceptible to novobiocin and to bacitracin, although the zone of inhibition to the "A" disk is often small (as shown in this photograph).
The sickling phenomenon observed in erythrocytes containing hemoglobin S may be induced by which of the following? - ANSWER- Reducing agents actually induce the sickling phenomenon in RBCs when they contain hemoglobin S.
If an autologous blood donor weighs 35 kg, how much blood can be collected for later transfusion? - ANSWER-315 mL
Volume to draw = (Donor's weight in kilograms / 50 kg (minimum weight requirement) x 450 mL (volume of unit to be donated)
In this case, Volume to draw = (35 kg / 50 kg) x 450 mL = 315 mL
Which adipokine is decreased in obesity, is anti-inflammatory, and increases insulin sensitivity? - ANSWER-Adiponectin is a protective cytokine. This cytokine is anti-inflammatory and increases insulin sensitivity. Adiponectin is usually decreased in obesity.
