An evaluation of methods of screening for anaemia.

Screening methods for anaemia were selected for testing on the grounds of cheapness, simplicity, sturdiness, accuracy and independence of mains electricity or batteries. The methods evaluated were the copper sulfate method, the Dare haemoglobinometer, the Lovibond comparator, the A. O. Spencer haemoglobinometer, and the Tallqvist method. A new device, the Carib haemoglobin comparator, was developed. The Dare and Lovibond instruments were found to be inaccurate in the laboratory. The other instruments were tested by primary health care workers in clinics in Jamaica. The Carib haemoglobin comparator and the copper sulfate method were found to be accurate, easy to use, and cheap. Both methods are considered to be useful for screening for anaemia at primary health care level.
