| Popis: | Background: Mutations affecting transcription, translation, or beta-globin stability, among other stages of beta-globin production, cause beta-thalassemia. Methods: Beta-thalassemia results in a high red blood cell count with a low mean corpuscular volume (60–70fl) and mean corpuscular hemoglobin (19–23pg), and Naked Eye Single Tube Red Cell Osmotic Fragility Test (NESTROFT) is recommended for mass screening of populations. Among tribals in Dharmapuri district, this cross-sectional analysis evaluated the efficacy of RBC and NESTROFT against HPLC, regarded as the gold standard, in a study involving 484 subjects. Results: Findings indicated that out of the 484 samples, 73 tested positive for the beta-thalassemia trait through HPLC. The NESTROFT test demonstrated 87% sensitivity, 98.5% specificity, a positive predictive value of 99.3%, and a negative predictive value of 73.3%. In the multivariate analysis, NESTROFT and hemoglobin showed high significance with P values of 0.003 and 0.000, respectively. Conclusion: NESTROFT’s high sensitivity is particularly noteworthy due to the absence of research among the Malayali tribes in the Dharmapuri district. Adoption of this preliminary test shows promise in detecting the disease at the local level, providing important information for early detection, especially considering the sizeable tribal population. |
