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 interpretions can be made? (select one or more options)

1. Consistent with a single species P.falciparum infection
2. Consistent with a single species non-P.falciparum infection
3. Most consistent with a dual species infection including P.falciparum
4. Most consistent with a dual species infection not including P.falciparum
5. Most consistent with a dual species infection not including P.falciparum
6. 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
