Test devices are overly sensitive to handling and storage	Sometimes they say if it has been in your bag, it has been exposed to heat, you use it and you find it will not show anything (Participant 3, focus group Junior Nurses)
POC tests have low sensitivity and specificity	… you can test for malaria, the RDT [rapid diagnostic test] is negative, the clinical symptoms are malaria, and you do a BS [blood smear microscopy] and they find it positive (Participant 6, focus group Senior Nurses)
Some tests falsely signal previous infections as active ones	… the challenge I have with these point-of-care tests is that some of them remain positive even after the infection has been cleared. (Participant 3, focus group Lab Workers)
Test results can be unclear, allowing disagreement between users	One technician will say it is faint and in most cases when it is faint, people will begin to argue about it. One will say negative and another one will say positive. (Participant 8, focus group Lab Workers)
