Serological antibody testing measures IgM, IgG, or IgA antibodies in the bloodstream. It helps assess current or past infections.
Antibody Testing Market Overview and Growth Dynamics
The antibody testing market was valued at US$ 7,260.00 million in 2021 and is projected to reach US$ 11,578.47 million by 2028, registering a CAGR of 6.9% during the forecast period. Antibodies are immunoglobulins, Y shaped proteins produced by the immune system to identify and neutralize harmful pathogens. Antibody tests, also known as serological tests, are used to detect the presence of antibodies in the blood, indicating prior exposure to infections or response to vaccination.
The market growth is strongly supported by the rising global burden of infectious diseases, increasing awareness about early diagnosis, and the expanding geriatric population that is more vulnerable to chronic and infectious conditions. In addition, technological advancements in immunoassay platforms and government initiatives to strengthen diagnostic infrastructure are contributing significantly to market expansion.
Impact of COVID 19 on Market Expansion
The COVID 19 pandemic played a transformative role in accelerating the demand for antibody testing worldwide. After SARS CoV 2 was declared a public health emergency of international concern in January 2020, rapid and large scale testing became essential to control the spread of infection. Along with RT PCR tests, antibody tests emerged as critical tools for disease surveillance, epidemiological studies, and immunity assessment.
Antibody detection kits enabled healthcare providers to determine whether individuals had developed antibodies against SARS CoV 2. This supported clinical decision making, plasma therapy considerations, and return to work strategies. The emergency use authorizations granted by regulatory authorities such as the US Food and Drug Administration encouraged manufacturers to develop and commercialize innovative serology kits, which significantly boosted market revenues during the pandemic period.
