Understanding Immunoassay Testing

Immunoassays are biochemical tests used to detect the presence or concentration of a substance, typically proteins or hormones, in a sample. These tests rely on the specific binding between an antigen (target molecule) and an antibody, enabling the detection of disease markers or monitoring of therapeutic drugs.

How Immunoassays Work

The basic principle of an immunoassay involves an antigen-antibody reaction. Here’s how it generally works:

1. Sample Addition: A sample (like blood serum) is added to the test chamber containing antibodies that are specific to the target antigen.


2. Binding Reaction: If the target antigen is present, it will bind with the antibody.


3. Signal Generation: Once binding occurs, a signal is generated, often using a labeled molecule that emits light or color.


4. Detection and Quantification: The signal's intensity correlates to the amount of target antigen present, which is then quantified by the immunoassay system.

Types of Immunoassay Tests

There are various immunoassay formats, each with specific applications, including:

1. Enzyme-Linked Immunosorbent Assay (ELISA): Often used for hormone and infectious disease testing, ELISA is known for its sensitivity and specificity.


2. Radioimmunoassay (RIA): This highly sensitive assay uses radioactive labels and is effective for detecting hormones and drugs at low concentrations.


3. Chemiluminescent Immunoassay (CLIA): The Beckman Access 2 utilizes CLIA technology, which emits light to detect and measure analytes, providing high sensitivity and rapid results.

Common Tests Conducted on the Beckman Access 2

The Access 2 Immunoassay System supports various critical tests, including:

1. Thyroid Function Tests: Measures hormones such as TSH, T3, and T4 to diagnose thyroid disorders.


2. Tumor Marker Tests: Includes tests like PSA (Prostate-Specific Antigen) and CA-125, useful in detecting and monitoring cancer.


3. Cardiac Marker Tests: Detects markers like Troponin, helping diagnose heart attacks and other cardiac conditions.


4. Fertility and Reproductive Hormones: Measures hormones like LH, FSH, and beta-hCG, crucial for fertility assessments.


5. Infectious Disease Testing: Detects antibodies or antigens for infectious agents, aiding in diagnosing infections like hepatitis and HIV.
