ozambique, in August 2010. The first site was the central
hospital (Hospital Central de Maputo), where 139 patient
samples were collected and analyzed in triplicate. The
second site was a smaller clinic (A Clínica de Saúde de Alto
Maé) where 66 patient samples were collected and analyzed
in triplicate. All blood samples were collected from patients
who had come to the hospital or clinic for reasons requiring
a blood draw and no additional blood collection was
performed in connection with this study. All blood samples
used in this study were coded upon collection to ensure
patient anonymity.
