BACKGROUND

Platelet rich plasma (PRP) is increasingly used as an adjunct treatment for androgenetic alopecia (AGA). PRP preparation involves anticoagulant tubes, such as PRP kits or regular tubes such as EDTA. Studies have shown that platelet concentration in PRP correlates with the growth factors present. However, there is limited data regarding the platelet yield across different anticoagulant tubes. This study will aid in the use of EDTA tube as an alternative to the commercially available PRP kits.

OBJECTIVE

This study aims to determine the platelet concentration level obtained in EDTA tubes versus the commercially available PRP kit in patients with AGA.

METHODOLOGY

This was a cross-sectional, quantitative study in 27 adult males with AGA. The venous blood extracted were placed in EDTA and PRP kit tubes and were centrifuged. A hemoanalyzer was used to obtain the platelet concentration levels. Statistical analyses using paired t-test was performed using the STATA MP Software.

RESULTS

Comparative analyses indicated that the mean difference in platelet concentration between the PRP kit and EDTA was -472.67 (95% Cl = -575.40 to - 369.93). Thus, the mean platelet concentration (t=-9.46, p=0.001) was statistically different between the two groups with a significantly higher mean platelet concentration with EDTA as compared to the PRP kit.

CONCLUSION

The platelet concentration levels obtained from the EDTA tubes were higher than the PRP kit. Thus, the EDTA tube may be a good alternative to the costly commercially available PRP kit.
