Table 4 Frequency of PfHRP2 sequence groups based on the Baker’s model and PfHRP2 RDT results (n = 48)

From: Genetic variation of Plasmodium falciparum histidine-rich protein 2 and 3 in Assosa zone, Ethiopia: its impact on the performance of malaria rapid diagnostic tests

Group Frequency (N = 48) Prediction of PfHRP2 RDT Positivity Microscopy
 > 250 parasite/µl
No (%) No (%) No (%)
A 11 (22.9) 8 (72.7) 8 (100)
B 26 (54.2) 19 (73.1) 14 (73.7)
C 10 (20.8) 7 (70.0) 6 (85.7)
I 1 (2.1) 1 (100) 1 (100)
  1. PfHRP2 sequence isolates were classified into four groups according to the frequency number of types 2 × type 7 repeats: group A (≥ 100, very sensitive), group B (50–99, sensitive), group C (< 43, non-sensitive) and group I (44–49, borderline) as describe previously (Baker et al. [8])
