Interpreting Results

Positive Reading

Two lines appear in the main window. Line in Control Region (C) and any visible line in Test Region (T). A very faint line in the Test region (T) is also still considered to be a positive result.

If a positive result is obtained, visit a COVID-19 clinic for a PCR rest immediately to confirm the result.

Negative Result

One line appears in Control Region (C) and no apparent line in Test Region (T).

Invalid Result

No line in Control Region (C), with or without a line in the Test Region (T).

  • Results from any test which has not produced a Control band at the specified read time must be discarded.

  • If the problem persists, discontinue using the kit immediately and contact your supplier.
