Enzyme-Linked Immunosorbent Assay (ELISA) plays a crucial role in the diagnosis and monitoring of AIDS (Acquired Immunodeficiency Syndrome) within the field of biotechnology. Here’s a brief overview:

Role of ELISA in AIDS:

1. Diagnosis:
   • Detection of HIV Antibodies: ELISA is commonly used to detect antibodies against HIV (Human Immunodeficiency Virus) in blood samples. The presence of these antibodies indicates an HIV infection, which can progress to AIDS.
   • Screening Tool: It serves as a primary screening tool due to its high sensitivity and specificity. Positive results are usually confirmed with more specific tests like Western Blot.
2. Monitoring:
   • Viral Load Monitoring: While ELISA primarily detects antibodies, advancements have led to its use in quantifying viral load by detecting HIV antigens, helping monitor disease progression and response to treatment.
3. Blood Safety:
   • Blood Donation Screening: ELISA is vital in screening donated blood for HIV, ensuring the safety of blood transfusions and preventing the spread of HIV through contaminated blood products.
4. Research and Development:
   • Vaccine Development: ELISA is used in research to evaluate the efficacy of potential HIV vaccines by measuring immune responses in clinical trials.
   • Biomarker Identification: It aids in identifying biomarkers for disease progression and treatment efficacy.
