  1. aNumbers represent the amount of samples with a specific test result (between brackets as the percentage of total number of samples tested).
  2. bThe Kisumu sample set comprised urine samples of 113 individuals which were tested with the UCAA10 and UCAA250 assay. A non-random subset of 73 samples was also tested with UCAA2000 assay (not included in this subset were 10 samples that scored a positive test result with both, UCAA10 and UCAA250, plus 30 samples that scored a negative test result with the UCAA250).
