FBC for Dengue Monitoring in Malaysian Clinics

Dengue is why many Malaysian GPs bring the FBC in-house. Here is what the analyser tracks, and where its role stops.

What the FBC shows in dengue

Platelets

A falling platelet count is typical as dengue progresses. Serial counts show the trend.

Haematocrit

A rising haematocrit together with a rapid fall in platelets is recognised as a warning sign of plasma leakage.

White cells

A low white-cell count is common early in dengue.

Why an in-house FBC helps

  • Results during the visit, so the doctor can decide on referral the same day.
  • Repeat counts on follow-up visits without waiting for an outside lab.
  • No courier delays during dengue season peaks.

What it does not do

An FBC does not diagnose dengue. Diagnosis uses tests such as NS1 antigen and dengue serology, and patient management follows the Ministry of Health’s clinical practice guidelines and the doctor’s judgement.

Frequently asked questions

Can an FBC machine diagnose dengue?
No. It tracks platelets, haematocrit and white cells; dengue is diagnosed with NS1 antigen or serology tests.
Which FBC machine suits a clinic that sees dengue?
A compact 3-part analyser gives platelet, haematocrit and white-cell counts, which cover dengue monitoring for most GP clinics.
How accurate are low platelet counts on clinic analysers?
Modern analysers count low platelets well, but clumped samples or very low counts should be checked with a blood film.
