One can define immunoassay as a biochemical test which is performed for measuring the concentration of substances like hormones, antigens, etc. in the body by using samples of biological liquid like urine, saliva, and serum. These tests are performed by using immunological reactions and are highly specific as well as sensitive. Calbiotech offers its customers a wide range of products and services at transparent prices. These products are efficient as they help the patients in determining the accurate quantity of analytes that have a very small concentration in the body.


Calbiotech is the specialist of immunoassay services and believes in focusing on break-through research which is the foundation of company’s success. Immunoassay tests are also used for conducting pregnancy tests. These tests detect the existence of human chorionic gonadotropin in the sample. As these tests are highly efficient, they can detect the pregnancy within the 48 hours of fertilization. At Calbiotech, experts define immunoassay as a chemical technique which is helpful to the patients in detecting any specific substance through a specific immunological reaction.


A large number of immunoassay tests namely Radioimmunoassay, Enzyme (EIA) immunoassay, Particle immunoassays and many more exist in the market these days. In the radioimmunoassay technique, a radioactive isotope is labeled as an antigen or an antibody. This technique is highly susceptible, well established, and it easily detects the presence of an analyte. EIA is the alternative for RIA and is used in order to detect the presence of any type of infectious disease in the body. In it, enzyme is labeled as a antigen or antibody. Though this technique is highly efficient as well as beneficial, however, it is mandatory to take some precautions while performing these tests like blood sample should always be collected in a tube which contains no additive. Similarly, pregnant women should avoid working where RIA tests are performed. To know more about the immunoassay services offered by the company, please visit www.calbiotech.com
