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?

Phase of reactivity is primarily at immediate spin (4+) and reactions get weaker at AHG (w+). There is no specific pattern of reactivity and the auto control is negative which rules out an autoantibody. This is a strong cold antibody which is still slightly present after incubation and washing.
Activation and binding of the antibody takes place at room temperature or colder. Eliminating this phase will prevent the antibody from binding. Cold antibodies usually are more of a nuisance to blood bankers and are not clinically significant.
When performing an antibody screen, both the screen cells are 4+ at immediate spin and W+ at AHG. The antibody panel shows 4+ reactions at immediate spin and W+ reactions at AHG and there is no specific match to the reaction pattern. The auto control is negative. What would be a logical next step?

In which of the following laboratory situations is a verbal report permissible?

High triglycerides may be caused by disorders such as type 2 diabetes, hypothyroidism, Cushing's sydnrome, liver disease, uremia, dysglobulinemia, nephrotic syndrome, and alcoholism can cause hypertriglyceridemia.
A 46-year old known alcoholic with liver damage is brought in the ER unconscious. One would expect his lipid values to be affected in what way?

The primary mechanism responsible for glomerular filtration is:
