Antibody Count
An antibody count is the number of antibodies present in a person's blood. Antibodies are proteins produced by the immune system that help fight off infections and other foreign substances. The normal range for antibody count varies depending on the person's age, gender, and medical history. Generally, a positive antibody count indicates an active immune response to a foreign substance or infection. Higher antibody counts are often associated with greater protection from infection.
Titer
The titer is the measure of the amount of antibodies present in a person's blood. It is expressed as a ratio, with the amount of antibodies in the sample divided by the amount of antibodies found in a healthy person's sample. A titer of 1:1 indicates that the amount of antibodies present in the person's sample is the same as what would be found in a healthy person's sample. A titer of 2:1 indicates that the antibody count in the sample is twice the amount found in a healthy person's sample.
Normal Range
The normal range for antibody count varies based on a person's age, gender, and medical history. Generally, a positive antibody count is considered to be above 1:1. Higher antibody counts are often associated with greater protection from infection. However, it is important to note that the normal range may differ for each individual, and a high antibody count does not always guarantee protection from infection.
