What do we use to cover the tube before inverting to mix the blood and NSS?

Centrifuge minute and rpm of washing red cells?

How many total of washes should you do?

A proper red cell suspension has a tomato red color?

What is the purpose of adding NSS?

A series of simple dilutions in which the concentration of a substance decreases by the same quantity in each successive step.

Serial Dilution is important in the determination of the antigen titer.

Reported as the reciprocal of the highest dilution of the patient's serum in which the antibody is still detectable.

Grading agglutination: 0

Grading agglutination: W+

Grading agglutination: 1+

Grading agglutination: 2+

Grading agglutination: 3+

What are the two methods through which the ABO forward grouping procedure is performed:

Other names for reverse typing?

In this procedure the medical technologist detects the unknown antibodies present in the patient's serum by using red cells of known antigenic specificity.

Dolichos biflorus is also known as?

Who developed the gel technology method?

In what year did Dr. Lapierre developed the method of gel card technology?

What did Gel card technology used to trap agglutinated red cells?

Gel card technology uses the subsequent interpretation of?

Certain blood groups substances, namely A, B and H, occur in soluble form in secretions such as saliva in a large population of individuals, these referred to as?

What is the reaction termed when water soluble substances neutralize or inhibit the capacity of their corresponding antibodies to agglutinate erythrocytes possessing the corresponding antigen?

In the collection and preparation of saliva why do we need to heat the specimen in a boiling water for 10 minutes?

The absence of agglutination in saliva is a positive result of the presence of ABH antigen and indicates that an individual is a secretor?

What is the purpose of dilution in testing the secretor status of saliva?
