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 are reasonable interpretions?

Consistent with a single species P.falciparum infection
Consistent with a single species non-P.falciparum infection
Most consistent with a dual species infection including P.falciparum
Most consistent with a dual species infection not including P.falciparum
Most consistent with a dual species infection not including P.falciparum
An unreportable test


Explanation of correct answer (click "Expand")
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
