An antithetical relationship exists between the antigens M and N. Antithetical relationships occur in situations where for a given locus, only one of two genes may be inherited, the alleles are termed antithetical alleles.

In immunohematology, an antithetical relationship exists between M antigen and which of these antigens?

Lipids tend to form a "maltese cross" pattern when viewed in polarized light, which helps to differentiate them from other urine microscopic components.

Substances found in urinary sediment that are more easily distinguished by use of polarized microscope are:

The combination of complement C4, C2 and C3 that binds to the antigen-antibody complex in the initial reaction step in the classical pathway of complement activation is called the activation unit.

Which of the following is the "activation unit" in the classical complement pathway?

Serum ferritin is a good indicator of iron deficiency. However, it acts like an acute phase reactant, being elevated in a large number of conditions. Patients who have iron deficiency as well as another condition that elevates serum ferritin levels may therefore have normal or even elevated serum ferritin levels.

Which one of the following statements about serum ferritin are true:

The body compensates for alkalosis or acidosis of the blood PRIMARILY to regain a normal pH, between 7.35 - 7.45.

When the body compensates for a respiratory or metabolic disorder, the MAIN goal is to achieve:

As magnification INCREASES, the field of view will...

Though automated extraction machines have many benefits over manual methods the costs are high and generally require a high throughput of samples in order to justify the costs.

Automated extraction has many benefits over the traditional manual methods. The most important benefit is that the nucleic acid isolated is constantly consistent. There is a reduced amount of manipulation with dramatically decreases the chance of cross contamination. Also, automated extraction machines are considered moderate complexity and can be performed by a wider variety of laboratory professionals.

All of the following are considered benefits of automated isolation and extraction equipment EXCEPT:

DAT ( Direct Antiglobulin Test ).

When AHG or Coombs serum is used to demonstrate that red cells are antibody coated in vivo, the procedure is termed:

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?

Match terms with fragments resulting from papain digestion of an IgG molecule:

A = Fab fragment OR Fc fragment

B = Fab fragment OR Fc fragment

Sterile yellow stopper tubes contain thixotropic gel and a clot activator.

Twelve weeks after onset of the disease, patients with uncomplicated acute hepatitis B usually will demonstrate which of the following in their serum?

Fresh frozen plasma must be thawed at a maximum of 37oC in a water bath or similar equipment that has been validated and is temperature monitored. When using a water bath, the FFP should be wrapped in a plastic liner. After thawing, it is recommended that the FFP be administered immediately, preferably within 2 hours post-thaw.

The BEST way to thaw Fresh Frozen Plasma is to thaw it by:

This patient is most likely suffering from sickle cell anemia. This cell, which is sickle-shaped, is indicative of the presence of hemoglobin S. Polychromasia is also commonly observed in sickle cell anemia.
