Iron deficiency anemia, or IDA, is associated with an increased TIBC as there is less iron to bind to transferrin. Microcytic, hypochromic red cell morphology, a decreased serum iron level, a decreased serum ferritin level, and a decreased hemoglobin level are all characteristics associated with IDA.

All of the following are characteristic findings in patients with iron deficiency anemia EXCEPT:

A quality control program is to be set up for the following tests:

Phenylalanine deaminase (PAD)

Indole production

Voges-Proskauer (V-P)

Which pair of stock culture organisms would be MOST suitable to verify the performance of these three tests?

In which disorder do neonates demonstrate the presence of Bart ' s hemoglobin that changes to beta chain tetramers in adults?

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?

Hepatitis B surface antigen, or HBs, is a protein that is present on the surface of the virus. The protein will be present via laboratory testing in the blood with acute and chronic HBV infections

Immunology

What sero-marker is the first marker to become positive in Hepatitis B and is associated with the infective stage?

The role of provider-performed microscopy (PPM) is the

Platelet neutralization tests are one of the confirmatory tests that can be used to determine if a patient has a circulating lupus antibody, or lupus anticoagulant. The principle in this test involved the use of a freeze-thawed platelet suspension that, when mixed with the patient plasma, will neutralize the anti-phospholipid antibodies (lupus anticoagulant) present and allow for a corrected aPTT result upon re-testing.

A patient has a history of repeated spontaneous abortion. Coagulation studies reveal an elevated APTT, normal PT, normal platelet function, and normal clotting time. Schistocytes were seen on the peripheral blood smear.

Which test should be performed to determine if the patient has lupus anticoagulant?

Autologous units must be drawn before they are needed, and must be readily available, therefore are generally not of use in emergencies.

All of the following are benefits of autologous donation except:

The tube of choice for trace metal analysis is:

In an alkaline medium, potassium ferricyanide oxidizes hemoglobin to methemoglobin. Further reaction with potassium cyanide produces cyanmethemoglobin which has a maximum absorbance at 540 nm. Color intensity is proportional to total hemoglobin concentration, which is how the hemoglobin levels are measured.

Hematology

In the hemoglobin methodology using potassium ferricyanide the following measurable reaction occurs:

Electrophoresis uses an electric field to separate molecules based on differences in net electrical charge. The rate of electrophoretic migration is also dependent on the ionic radius of the molecule, the viscosity of the solution through which it is migrating, the electrical field strength, temperature, and the type of supporting medium used.

Electrophoretic separation fundamentally relies on:

FAB M5 is acute monoblastic leukemia

FAB M1 is acute myeloblastic leukemia without maturation

FAB M3 is acute promyelocytic leukemia

FAB M4 is acute myelomonocytic leukemia

Which FAB designation is called the " true " monocytic leukemia and is characterized by monoblasts, promonocytes, and monocytes?

MCH is the average weight of hemoglobin in the average red blood cell. The value is expressed in picograms (10-12 grams).

Hematology

Hemoglobin (g/100ml) x 10 / RBC count (millions/mm3) is the formula for calculating:

Which area of the laboratory can analyze a patient sample and be able to predict their risk of developing a disease?

The ratio of blood to anticoagulant in a light blue stopper tube is:
