<p>Representative amplifications experiments using serial dilutions of samples of known parasitaemia (quantified using the WHO International Standard as calibrator). Mean time to turbidity in minutes as follows: 10,000 p/μL = 17.5; 1,000 p/μL = 18.5; 100 p/μL = 19.4; 10 p/μL = 21.3; 1 p/μL = 22.9.</p
