The evaluation and validation of Phadebas paper as a presumptive screening tool for saliva on forensic exhibits.

The Phadebas Forensic Press Test is routinely used for the detection of saliva. However, assessment of the use of Phadebas paper for this purpose has not been studied extensively. The suitability of Phadebas paper as a presumptive screening tool for saliva on forensic exhibits, was investigated by analysing the following: (1) sensitivity, (2) specificity, (3) effects of temperature on sensitivity and specificity, (4) detection of saliva in mixed body fluid samples, and (5) influence of substrate porosity.
