Normal values in adult Zambians: IX. anti-streptolysin-o-titres.
Figures on normal values of Anti-Streptolysin-O-Titres are not available for most parts of Africa. This is certainly so for Zambia. The purpose of this paper is to produce reference figures for the normal adult. The results indicate that the curve is skewed towards the lower values and that 75% of values are 1:100 or below. If the sera of all subjects showing titres of 1:200 are considered however 93% of all cases studied are included. It is therefore concluded that this is the upper limit of normal and that figures above 1:200 must be regarded as abnormal.
