- Title
XCAT (Capillary Analysis Test) Validation Study: Practical Field Use of Presumptive Gunshot Residue Test.
- Authors
Newell, Ashleigh M.
- Abstract
The purpose of this study is to evaluate the effectiveness of RedXDefense’s XCAT (capillary analysis test) device in the detection of gunshot residue (GSR) on an individual’s hands in the field. During this study, various time frames were introduced between the deposit of the GSR and the collection of the sample, as well as the amount of GSR deposited. Several outside agencies were contacted to create a sufficient background of the current use of the XCAT; however, it was found that little research currently exists outside of the manufacturer’s laboratory tests. Field tests were conducted to verify the use of the device, which raised concern regarding the use of the XCAT as a tool to assist in eliminating or possibly identifying a suspect. In conclusion, on the basis of the performance of this device, the XCAT is not recommended for use in the field at this time.
