Methodology: A random selection blood sample was done for this study for a period of one month from July 24th 2017 to August 24th 2017. Blood bags were numbered 1-87 and picked amongst unnumbered blood bags by each donor in order of donation. The samples obtained were subjected to centrifugation and serum used in the immunoassay test by using the Chlamydia trachomatis IgG/IgM Elisa test kit. Results: This study showed that C. trachomatis was present in 8% (7 samples) of the blood samples analyzed and 92% were found to be negative. Conclusion: With 8% of the samples testing positive for Chlamydia trachomatis this indicated that some of the blood donated to the Regional Transfusion Center is contaminated.en-USArticle
