BI of patient vs BI of individual sites.

ABSTRACT

An analysis of 200 skin smear results from multibacillary patients showed that the average bacteriological index (BI) of a patient varied considerably from his site-wise highest BI. The average BI was equal to site wise highest BI only in 17.5% of cases and in the rest, it ranged from 99% to as low as 36% of the highest site-wise BI. In follow-up smears, site-wise consistency of the highest BI was found in 96% of cases. It is suggested that for follow-up purposes, repeating smear from only one such site would be adequate.
