What is this test?
The catalogue describes a rapid latex screen for heterophile antibodies when infectious mononucleosis is suspected. It is an orienting test and does not directly detect Epstein-Barr virus.
Why might it be ordered?
- For symptoms that lead a clinician to consider infectious mononucleosis.
- For an initial assessment before EBV-specific markers when those are needed.
What sample is needed?
A heterophile-antibody test normally uses blood, but the catalogue does not state the exact material. Confirm whether venous or capillary blood is required.
How should you prepare?
Special dietary preparation is usually unnecessary. Report how many days symptoms have been present and the patient's age because timing and age affect reliability.
How should you understand the result?
A reactive result detects heterophile antibodies and may support a typical mononucleosis picture, but it does not confirm EBV itself. A non-reactive result does not exclude illness, especially early or in children.
