... present at d ays 42 and 134 and were boosted by re-infection (day 167). Anti-p30 reac- tivity was barely detectable at day 42 and 134 and was substantially boosted post-reinfection (day 167). These results ... sensitivity of the p30 assay was slightly lower due to the combination of reduced analytic sensitivity and the delayed kinetics of the anti-p30 response. However, the p3...
