ABSTRACT
The Naked Eye Single Tube Red Cell Osmotic Fragility Test (NESTROFT) was applied to 4 groups of subjects:
(i) Normal; (ii) Proven beta-thalassemia trait carriers; (iii) Iron deficiency anemia; and (iv) other hemoglobinopathies, to evaluate its effectiveness as a screening test for beta-thalassemia minor. The test was successful in detecting 105/110 subjects with beta-thalassemia trait. The sensitivity of the test was 95.5% and specificity was 87%. The predictive value of the positive test was 70.5% and that of the negative test was 98.3%. NESTROFT was also positive in 9/17 subjects with HbS trait, in 3/3 subjects with HbD trait and in 1/1 subjects with HbE trait. The test proved to be simple, cheap, easy to perform and adaptable for field surveys, coming close to an ideal screening test for beta-thalassemia minor.
