Mean and 95% posterior credible intervals (PCI) for the sensitivity (Se) and specificity (Sp) of serial and parallel testing using one serum ELISA and the fecal PCR

		Mean (95% PCI)
		ELISA A – Fecal qPCR	ELISA B – Fecal qPCR
Serial testing	Seser	8.7 (3.8; 15.8)	8.5 (3.5; 16.0)
	Spser	99.8 (99.3 – 100.0)	99.3 (98.5; 99.9)
Parallel testing	Separ	56.6 (38.8;76.1)	55.8 (37.4; 75.9)
	Sppar	93.8 (91.8; 95.6)	93.1 (90.7; 95.1)

Estimates were obtained with model 1, with doubtful ELISA results and fecal qPCR Ct ≤ 42 treated as positive
