Table 4.

Comparison of Cryptosporidium spp. sensitivity between whole stool samples and stool samples stored on Whatman protein saver cards

Application method	DNA extraction method	High parasite load* (N=10)	Low Parasite Load† (N=10)	All samples (N = 20)
Application method	DNA extraction method	Sensitivity (95% CI)	Sensitivity (95% CI)	Sensitivity (95% CI)
Whole stool directly on Whatman cards	Qiagen	80% (95% CI: 44%, 97%)	0% (95% CI: 0%, 31%)	40% (95% CI: 19%, 64%)
Whole stool directly on Whatman cards	Chelex	50% (95% CI: 19%, 81%)	0% (95% CI: 0%, 31%)	25% (95% CI: 9%, 49%)
Stool suspension on Whatman cards	Qiagen	70% (95% CI: 35%, 93%)	0% (95% CI: 0%, 31%)	35% (95% CI: 15%, 59%)
Stool suspension on Whatman cards	Chelex	70% (95% CI: 25%, 93%)	0% (95% CI: 0%, 31%)	35% (95% CI: 15%, 59%)

CI = confidence interval.

* Whole stool ct value < 30.

† Whole stool ct value ≥ 30.
