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)?

Glycoprotein IIb/IIIa is integral in the process of platelet aggregation as well as clot retraction.

A defective clot retraction might be caused by which one of these?

Gluconeogenesis is the formation of glucose from noncarbohydrates when carbohydrate intake is absent, a fasting state. The hormone cortisol along with glucagon and epinephrine all stimulate this metabolic pathway. Insulin; however, inhibits this pathway and is therefore the correct answer.

Which of the following hormones inhibits gluconeogenesis, the formation of glucose from noncarbohydrate sources such as amino acids, glycerol, and fatty acids?

Medical Technology is the profession concerned with performing laboratory analyses

Secondary granules, also known as specific granules first appear in the myelocyte stage next to the nucleus. In neutrophils this is termed the "dawn of neutrophilia".

What is one of the main characteristics of secondary granules in the neutrophilic granulocyte cytoplasm?

The body of a tapeworm is composed of successive segments known as proglottids. Each mature proglottid has both male and female reproductive structures.

What is the anatomical feature of a tapeworm that possesses both male and female reproductive structures?

Calcium oxalates can be found in normal urine in varying pH levels. Ammonium biurate and triple phosphate can be found in normal alkaline urine. Leucine crystals are always abnormal, and can be found in maple syrup urine disease.

Which one of the following crystals is NOT found in normal urine?

Acute hemolytic transfusion reactions are most commonly due to ABO-incompatible blood being transfused to a recipient with naturally occurring ABO alloantibodies (anti-A, anti-B, anti A,B).

Acute intravascular hemolysis as the result of a blood transfusion is most often associated with which of the following causes?

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.

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?

The coagulation department tests samples for:

Which of the following genotypes cause beta thalassemia minor?

A hapten is an incomplete antigen.

All of the following cellular antigens are important to an immunohematologist except:

Parathyroid hormone regulates serum calcium by acting on bone, kidney, and intestines while regulating phosphate by stimulating the intestines and the kidneys, enhancing absorption and reabsorption respectively.
