Figure 1. Visual example of reactivity of BSA-peptide P6 with sera on lateral flow.

Figure 1

Reactivity with one serum specimen from each of the groups of non-TB controls and TB patients included in the study with BSA-peptide conjugate P6 is shown. In general the serum specimens from non-TB subjects exhibited no detectable reactivity with the striped BSA-peptide conjugate while sera from smear positive TB patients produced test lines easily distinguished by the eye.
