Figure 2From: An assessment of various blood collection and transfer methods used for malaria rapid diagnostic testsTest band intensity of various RDTs using different blood volume and parasitaemia. At 200 parasites/μL blood, using less blood than the required volume did not give clearly visible test bands (less than 1 on the RDT rating chart). At 2000 parasites/μL blood, all RDTs gave visible test bands (1 or higher) in all the blood volumes used. Note that Optimal is designed to use 10 μL of blood, the other tests 5 μL.Back to article page
