Macroamylasemia can be diagnosed by measuring amylase levels in the urine and serum. In patients with macroamylasemia, there will be high levels of amylase in the serum. However, macroamylasemia can look similar to acute pancreatitis, which also causes high levels of amylase in the blood. To help differentiate, we measure amylase levels in the urine. Urine levels of amylase are low in people with macroamylasemia, but high in patients with pancreatitis.

The results which would be MOST consistent with macro-amylasemia are?

Glucagon and epinephrine promote glycogenolysis, conversion of glycogen to glucose, which increases plasma glucose.

Cortisol along with glucagon increases gluconeogenesis, formation of glucose from noncarbohydrates which also raises plasma glucose concentration.

Chem

Which of the following hormones increases plasma glucose concentration by converting glycogen to glucose? Please select all correct answers

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?

Delayed hemolytic transfusion reactions (DHTR) usually occur within which time period?

Which of the following tubes produces a serum sample?

Question options:

True Statements:

Urine should be well mixed prior to dipping the reagent strip. Prolonged immersion may wash out test reagents.

False Statements:

Urine should be centrifuged prior to dipping the reagent strip. When visually reading the reagent strip, all results can be read immediately after dipping the strip in the urine specimen.

Which of the following statements are TRUE regarding the reagent strip test procedure? (Choose ALL of the correct answers)

Gram positive organisms resist decolorization by ethyl alcohol. The large crystal violet-iodine complex is not able to penetrate the peptidoglycan layer, and is trapped within the cell in gram-positive organisms. Conversely, the outer membrane of gram-negative organisms is degraded and the thinner peptidoglycan layer of gram-negative cells is unable to retain the crystal violet-iodine complex and the color is lost.

What is the purpose of using ethyl alcohol or acetone in the gram stain procedure:

A blood culture to evaluate septicemia is performed in:

Alpha-fetoprotein is a substance typically used in the triple test during pregnancy and for screening chronic liver disease patients for hepatocellular carcinoma.

Increased concentrations of alpha-fetoprotein (AFP) in adults are MOST characteristically associated with:

The role of the point-of-care testing (POCT) compared with in-laboratory testing is the

All of the following activities are associated with platelets EXCEPT:

Anything that can cause significant turbidity in a blood sample, such as high leukocyte count or lipemia can potentially interfere with the accuracy of a spectrophotometric hemoglobin assay.

Hematology

Which of the following may interfere with the accurate measurement of hemoglobin:

The purpose of protective isolation is to protect:

Intravascular hemolysis is typically associated with increased levels of serum (plasma) LDH and bilirubin, and an increased number of reticulocytes. Serum LDH is found in higher levels during intravascular hemolysis due to fact that high levels of LDH are normally found within the red cells, but is now being spilled into the bloodstream via red cell lysis. Bilirubin is a breakdown product of hemoglobin, which has also been spilled into the bloodstream from broken red blood cells via hemolysis. Reticulocytosis is a reflection of the release of an increased number of immature red blood cells from the marrow to account for the red blood cells that are lost through hemolysis. This is a normal response. Failure to show an increased reticulocyte count with hemolytic episodes or hemorrhage would indicate an ineffective erythropoiesis (possible bone marrow function problem).

Which of these blood levels will increase during intravascular hemolysis?

Blood plasma will contain coagulation proteins, but not in a clotted tube where serum is present.

Blood serum contains each of the following substances except:
