A procedural control is included in the test. A red line appearing in
the control region (C) is the internal procedural control. It confirms
sufficient specimen volume and correct procedural technique.
Control standards are not supplied with this kit; however, it is
recommended that a positive control (containing 10 ng/mL HBsAg)
and a negative control (containing 0 ng/mL HBsAg) be tested as a
good laboratory practice to confirm the test procedure and to verify
proper test performance.
