RDT Quiz A Q2


Shown below is an RDT test. This uses a pan-malarial antibody (labelled Pan) and a P.falciparum species-specific antibody (labelled Sp). The test has been used to assess a patient and the positive bands are shown on the figure.

Which of the following interpretations can be made from this result? (select one or more options)

Single species: P.falciparum
Single species non-P.falciparum
Two species including P.falciparum
Two species not including P.falciparum
P.falciparum with HRP2 deletion
This test cannot be reported


Explanation of correct answer (click "Expand")
'Short answer taken from section "Multi-line RDT Interpretation" (see the section for full details and links).

When no band appears in the control area (black arrow) the test is ALWAYS invalid:

Irrespective of whether any other bands are present, this is always an invalid test: do not interpret. Report as failed test
Action:

  • Repeat the test
  • Consider the reasons for test failure
