ASCP ASCP-MLT Actual Free Exam Questions & Community Discussion

Refrigerated temperatures, those close to 4 ºC, are recommended for the preservation of enzyme activity in a patient sample.
Chemistry
The recommended storage temperature for the preservation of activity for MOST enzymes is:

The colonies seen growing on the bird seed agar appear smooth and have a distinct reddish-brown pigmentation. The active ingredient in bird seed (Guizotia abyssinica) agar is caffeic acid, which is extracted and placed in an agar containing 1% glucose. Of the cryptococci, and other species of yeasts, Cryptococcus neoformans selectively produces the enzyme phenoloxidase, which oxidizes the caffeic acid in the medium to melanin, producing the red-brown pigmentation.
The other yeast species included in this exercise do not possess phenoloxidase activity and therefore remain non-pigmented when grown on bird seed agar.
The colonies shown in this photograph were grown on Guizotia abyssinica (bird seed) agar at 30°C for 72 hours. The most likely identification is:

Free T4 is affected the least by changes in plasma proteins during pregnancy.
Which of the following thyroid function assays is affected least by pregnancy:

FFP that has been thawed at 30 - 37oC and maintained at 1 - 6oC must be transfused within 24 hours. In contrast, "Thawed Plasma" can be used for up to 5 days as a replacement therapy for patients requiring stable clotting factors. Keep in mind that these are two different component types and you are asked about FFP.
Blood Bank
FFP that has been thawed at 30 - 37oC and maintained at 1 - 6oC must be transfused within ___________ after it has been thawed.

The term that is used to describe the color in these tubes of CSF is "xanthochromia." Xanthochromia is an abnormal color, usually yellow, orange, or pink, in the supernatant of the CSF sample. It may indicate that a subarachnoid hemorrhage (SAH) has occurred.

Jaundice and icterus both describe a yellowing of the skin, mucous membranes, and eyes. Blood plasma/serum that is deep yellow is also described as icteric.
What term is used to describe the color in these tubes of cerebrospinal fluid (CSF)?

Primary- Target glands (such as thymus, thyroid, parathyroid, etc.)
Secondary- Pituitary gland
Tertiary- Hypothalamus
Match the type of endocrine dysfunction with the appropriate organ:
1. Target gland
2. Pituitary gland
3. Hypothalamus

What amount of absorbent material must be included between the primary receptacle and secondary packaging for either a category A or category B liquid specimen?

The Bethesda assay is used to measure the titer and activity of the antibody present in a patient's sample.
Prothrombin time is an initial screening procedure for bleeding disorders and a test used for monitoring anticoagulant therapy. A thrombin time is used to detect heparin interference in an aPTT mixing study. A mixing study is performed to detect the presence of a factor deficiency or coagulation inhibitor, but does not quantify the result.
Hematology
Which of the following tests is used to quantify a coagulation inhibitor?

High-sensitivity C-reactive protein (hs-CRP) is used as an aid in the diagnosis and treatment of cardiovascular disease (CVD). At low levels, it can detect those at risk for cardiac heart disease. At high levels in those with no history of heart disease, it indicates a high risk for acute myocardial infarction (AMI), stroke, or peripheral vascular disease. For patients with acute coronary syndrome (ACS) or stable coronary disease, hs-CRP is used to predict future coronary events.
Ranges of hs-CRP in prediction of risk for CVD are:
<1.0 mg/L Low CVD risk
1.0-3.0 mg/L Average risk for CVD
>3.0 mg/L High risk for future CVD
If results are >10.0 mg/L, the patient should be evaluated for an acute inflammatory condition.
Chemistry
A high-sensitivity C-reactive protein (hs-CRP) test result of 5 mg/L (normal = < 1 mg/L) may indicate which of the following?

The two main areas of the clinical laboratory are:
