7. Result (con.)

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

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

10. 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
