Product details.

The HBsAg (Hepa Card) is a one-step immunochromatographic sandwich assay for the qualitative detection of hepatitis B surface antigen (HBsAg) in serum or plasma. A monoclonal antibody gold conjugate and monoclonal solid-phase antibodies bind HBsAg to form a pink-purple test line, with a goat anti-mouse IgG control line. Manufactured at Reckon’s Vadodara facility under ISO 13485:2016 quality management, and released against reference standards before dispatch.

Procedure at a glance5 steps

Bring the card and the sample to room temperature, and lay the card flat.
Add 2 to 3 drops of serum or plasma to the sample well, without overflowing.
Let the reaction run until the lines appear, up to 20 minutes.
Read at 20 minutes; strong positives may show within 5 minutes.
C only is negative; C and T is positive for HBsAg, whatever the line intensities; no C line means the test is invalid.
