The HBsAb Rapid Test (Serum/Plasma) is a rapid visual immunoassay for the qualitative presumptive detection of HBsAb in human serum or plasma specimens. This kit is intended for use as an aid in the diagnosis of HBV infection.
Hepatitis B virus (HBV) is the most thoroughly characterized and complex hepatitis virus. The infective particle consists of a viral core plus an outer surface coat. HBV has at least 3 distinct antigen-antibody systems that can be tested: HBsAg, HBcAg, and HBeAg. HBV surface coat can be detected in serum as HBsAg. HBsAg characteristically appears during the incubation period, usually 1 to 6 weeks before clinical or biochemical illness develops, and implies infectivity of the blood. The corresponding protective antibody (anti-HBs or HBsAb) appears weeks or months later, after clinical recovery, and usually persists for life; thus, its detection indicates past HBV infection and relative immunity. Unfortunately, in 5 to 10% of patients, HBsAg persists and antibodies do not develop; these patients become asymptomatic carriers of the virus or develop chronic hepatitis. Since this antibody is recognized as the marker of immunity to HBV, the World Health Organization (WHO) includes a HBsAg diagnostic procurement program for the control of Hepatitis B. Many people, especially newborn infants, receive vaccination. The minimum standard titer of HBsAb for protective immunity to HBV is 10 mIU/mL.

Sample Collection&Storage
• The HBsAb Test is intended for use with human serum or plasma specimens only.
• Only clear, non-hemolyzed specimens are recommended for use with this test. Serum or plasma should be separated as soon as possible to avoid hemolysis.
• Perform testing immediately after specimen collection. Do not leave specimens at room temperature for prolonged periods. Serum and plasma specimens may be stored at 2-8°C for up to 3 days. For long term storage, specimens should be kept below -20°C.
• Bring specimens to room temperature prior to testing. Frozen specimens must be completely thawed and mixed well prior to testing. Avoid repeated freezing and thawing of specimens.
• If specimens are to be shipped, pack them in compliance with all applicable regulations for transportation of etiological agents.
• Icteric, lipemic, hemolysed, heat treated and contaminated sera may cause erroneous results.
Bring tests, specimens, and/or controls to room temperature (15-30°C) before use.
1. Remove the test from its sealed pouch, and place it on a clean, level surface. Label the device with patient or control identification. For best results, the assay should be performed within one hour.
2. Using the provided disposable pipette, transfer 2 drops of specimen to the specimen well (S) of the device and start the timer.
Avoid trapping air bubbles in the specimen well (S), and do not add any solution to the result window.
As the test begins to work, color will migrate across the membrane.
3. Wait for the colored band(s) to appear. The result should be read at 15 minutes. Do not interpret the result after 20 minutes.
