Abstract:
The present study was undertaken to assess the feasibility of whole dried blood spots to identify alpha-thalassemia-1 by PCR technique. Logistical constraints associated with sample collection and processing make the measurement of alpha-thalassemia-1 at community laboratories difficult. Dried blood spot samples provide a relatively convenient and minimally invasive means for collecting and transporting samples. We present Whatman 3 MM paper for spotting blood samples used for the first time for alpha-thalassemia-1 detection. Measurements of fresh EDTA whole blood and Whatman 3 MM dried blood spots prepared from venous blood were performed in 60 subjects. Whatman 3 MM dried blood spots results were precise and reliable. There was no actual difference in comparison to fresh EDTA whole blood samples. Whatman 3 MM dried blood spots for alpha-thalassemia-1 detection using the PCR technique showed no changes for 6 months.
