Suppose you performed this test and got agglutination with o antigen and sterile saline. eliminating contamination of the antigen and antiserum sample as a possibility; provide and explanation of this hypothetical result. is this attributable to poor sensitivity or specificity of the test system?

Here the sensitivity is very low that is the reason why the condition happened. The error resulted are not highly specific. The reason for binding is because the unnecessary binding occurred.
Agglutination between saline and O antigen shows that there is a contamination which is acting as an agglutination.
The contamination can present as an antiserum or as an antigen or may be in chemical or physical agents and they are termed as the responsible factors for agglutination.

Covalent bond is the correct answer

The virus is considered to be are living item since they have hereditary material dnas or rnas. they can imitate and change. they respond to boosts, for example, radiation, chemicals, and warmth. they have antigenic properties. they are proficient to duplicate with a same hereditary constituent.
