Table 2 Sensitivity and specificity of the lateral flow dipstick for detection of anti-PPDK antibodies in serum samples

Lateral flow dipstick test result	No. of serum samples that had been tested for the presence of anti-PPDK antibodies
	Positive	Negative	Total
Positive	26^a+b	0	26
Positive	(87%)*	0	26
Negative	4^a+b	40^c+d	44
Negative	4^a+b	(100%) **	44

^aGroup A sera : Seropositive and E. histolytica DNA detected in patients’ liver abscess samples.
^bGroup B: sera Seropositive and liver abscess samples non-available for DNA analysis.
^cHealthy individuals, Seronegative.
^dOther diseases: Seronegative (i.e.: pyogenic liver abscess, malaria, toxoplasmosis, leptospirosis, hydatidosis, filariasis and typhoid).
*Sensitivity tested with 30 sera from patients with ALA (Groups A and B).
**Specificity tested with 40 sera from healthy individuals and patients with other diseases.
