The HemoCue system consisted of a
portable, battery-operated photometer and a supply of
treated disposable cuvettes in which blood was collected.
The instrument is known to be stable and durable with a
sensitivity of 82.4% and specificity of 94.2%. Anaemia in
the study was defined by using the world health
organization and classified into mild anaemia (10–10.9g/dl),
moderate anaemia (7.0–9.9 g/dl) and severe anaemia (< 7.0
g/dl). Severe anaemic cases and those that could develop
into severe anaemia were referred to the
obstetrician/antenatal specialist clinic for further
assessment and appropriate management.
