Objective: The aim of this study was to compare the quantity and quality of platelets in platelet-rich plasma (PRP) samples prepared using three different reagents, namely, ethylenediaminetetraacetic acid (EDTA), sodium citrate, and acid citrate dextrose-A (ACD-A) solution. Materials and Methods: A prospective study was carried out in which all the 50 patients who attended the outpatient department for hair rejuvenation were enrolled for the study. All the patients had a history of hair fall with diffuse thinning of hair, Norwood Grades 2 and 3. Patients with complete hair loss were not included in the study. No specific randomization was carried out. All the patients were explained about the procedure and the use of vials containing the aforementioned three reagents. Then, 40mL blood was taken from each patient. Both quantitative and qualitative analyses of platelets were carried out on PRP samples. Quantitative analysis was done by using an automatic cell counter and cross-checking manually. Qualitative analysis was carried out by preparing smears from each of the three samples from each vial. All the patients were followed up at 4 weekly intervals for a duration of 6 months and then at the end of 1 year. All the patients received six sessions of PRP. Results: All the data were subjected to statistical analysis using Student's t-test, and P value of <0.001 was obtained in samples from ACD-A vials, which was statistically significant. In all the 50 patients, the samples collected in vials containing ACD-A yielded the maximum quantitative count and the best morphology of platelets under smear examination. Conclusion: Within the limits of this study, we would like to conclude that ACD-A vials should be used for collecting and processing blood for PRP preparation to obtain best results in hair rejuvenation.
