Introduction to Rotavirus Antigen Detection

Rotavirus is a leading cause of severe diarrhea among infants and young children, resulting in significant morbidity and mortality worldwide. Accurate and timely detection of rotavirus antigens is crucial for effective treatment and control.

Methods for Detecting Rotavirus Antigen

Enzyme-Linked Immunosorbent Assay (ELISA)

The Enzyme-Linked Immunosorbent Assay (ELISA) is a commonly used method for detecting rotavirus antigens in stool specimens. It offers high sensitivity and specificity rates of approximately 95% and 98% respectively. The assay involves the binding of rotavirus antigens to specific antibodies, followed by an enzyme-mediated color change for detection.

Polymerase Chain Reaction (PCR)

Polymerase Chain Reaction (PCR) detects the genetic material of rotavirus. It is highly sensitive with detection limits as low as 1-10 viral RNA copies per reaction. PCR provides rapid results and is capable of detecting multiple rotavirus strains. However, it requires specialized equipment and technical expertise.

Rapid Immunochromatographic Tests

Rapid Immunochromatographic Tests provide results in under 15 minutes, making them suitable for point-of-care diagnostics. These tests boast a sensitivity range of 85% to 95% and specificity between 90% to 95%. These tests use lateral flow immunoassay technology to detect rotavirus antigens.

QL Biotech Company Solutions

QL Biotech Company specializes in developing diagnostic kits for rotavirus detection. Their latest ELISA kit demonstrates a sensitivity of 97% and specificity of 99%. QL Biotech's rapid tests are designed to be user-friendly and provide results in 10 minutes with accuracy comparable to traditional methods.
