Summary Introduction

To analyze:

The reason for the higher titer value of Convalescent sera than Acute sera.

Introduction:

Human blood comprises of plasma, red blood cells, white blood cells and platelets. The serum can be defined as the plasma devoid of fibrinogens, red and white blood cells. The serum contains proteins, antibodies, antigens and hormones. For the purpose of diagnosis of various diseases serum of the patient is used. The serum contains antibodies which are the main reason for its usage in antibody titer tests like ELISA.

If the titer value obtained from the test is higher, it is an indication that the patient's immune response is good and the body contains a higher amount of antibodies whereas low titer values represent lesser antibodies and lesser immune response correspondingly.
