**Notes:**

^{a} A sample is considered detected only if all RDTs from both lots read by the first technician, at minimum specified reading time, are positive

^{b} Rate of positive test results for malaria when the results should have been negative. The number in parentheses indicates the total number of tests, being by default: Round 1, n=168; Round 2, n=200; Round 3, n=200; Round 4, n=232; Round 5, n=236

^{c} Round 1, n=79; Round 2, n=100; Round 3, n=99; Round 4, n=98; Round 5, n=100

^{d} Round 1, n=20; Round 2, n=40; Round 3, n=35; Round 4, n=34; Round 5, n=35

^{e} For combination tests, Pan or Pv line, only, positive indicates a false positive non P. falciparum infection. The number in parentheses indicates the total number of tests, being by default: Round 1 n=316; Round 2, n=400; Round 3, n=396; Round 4, n=392; Round 5, n=400

^{f} Pf line positive indicates a false positive P. falciparum infection. The number in parentheses indicates the total number of tests, being by default: Round 1, n=80; Round 2, n=160; Round 3, n=140; Round 4, n=136; Round 5, n=140

^{g} For combination tests, Pan or Pv line, only, positive indicates a false positive non-P. falciparum infection. The number in parentheses indicates the total number of tests, being by default: Round 1, n=158, Round 2, n=200; Round 3, n=198; Round 4, n=196; Round 5, n=200

^{h} Pf line positive indicates a false positive P. falciparum infection. The number in parentheses indicates the total number of tests, being by default: Round 1, n=40; Round 2, n=80, Round 3, n=70; Round 4, n=68; Round 5, n=70

^{i} Round 1, n=168; Round 2, n=200; Round 3, n=200; Round 4, n=232; Round 5, n=236

^{j} Product resubmission, results from most recent round of testing replace previous results. Refer to Table S1.

^{k} PDS presented in the table is based on a positive Pf test line (either HRP2 or Pf-pLDH). The results in brackets are the PDS based alone on HRP2 and Pf-pLDH test lines, respectively

^{l} Round 1, n=954; Round 2, n=1240; Round 3, n=1204; Round 4, n=1192; Round 5, n=1214

^{n} ARKRAY Healthcare Pvt. Ltd. was formerly Span Diagnostics Ltd.

^{p} PDS presented in the table is based on one of the positive test lines (either Pan-pLDH or Pv-pLDH). For test line specific results refer to the tables and annexes in the full reports.
