Introduction

comparison of two methods Acid phosphatase test Zinc test

Component of sperm Semen Acid Spermatozoa Enzyme (Protease, phosphatase) Semen Protein Seminal plasma Enzyme

174 cervicovaginal samples from consenting women Method 174 cervicovaginal samples from consenting women Cytology Acid phosphatase test Zinc test Statistical

Result

Result (con.)

Result (con.) Acid phosphatase - sensitivity 95% - specificity 96% - PPV 93% - NPV 98%

Result (con.) Zinc test - sensitivity 81% - specificity 54% - PPV 49% - NPV 84%

Discussion & Conclusion the acid phosphatase test has good sensitivity and specificity, and above all that it has a negative predictive value of 98% It is thus valuable as a screening test the longest timespan after which detection was possible was 106 h between intercourse and sampling

Discussion & Conclusion

Thank you
