"Introduction: It would be useful to analyse the existing data of volun-tary blood donors in a way that en-ables association of some factors with positive screening tests for transfusion Transmitted Infections (TTI) among voluntary blood do-nors
Objectives: This study conducted to assess positivity for transfusion transmitted infections among vol-untary blood donors.
Material & Methods: Case Control study, on voluntary blood donorsof camps during the year 2015with TTIs, while controls are two age matched controls without TTIs.
Observations: The frequency of previous blood donation was statis-tically significantly different be-tween cases and controls. None of the biological or socio demographic variable could determine the in-creased risk or protection for TTIs. Different variables showed variable sensitivity, specificity and predic-tive values for TTIs.
Conclusion: Selected sociodemo-graphic risk factors suggested by many epidemiological studies did not appear significant when tested with screening tests for a few dis-eases like Hepatitis B, C infection, Syphilis and HIV infections in case of voluntary blood donors."
