Reasons for Sample Rejection

Fingerprints

Quality fingerprints are extremely important!

In order to ensure that all demographic information about the person is correct (as compared to aliases, false identities, etc.), the fingerprints collected during DNA sampling are compared with the fingerprints on file in the Crime Records department at TX DPS.

The fingerprints are compared with the crime record associated with the SID # and/or name/DOB listed on the DNA datacard. Therefore, it is extremely important that the name, DOB, SID # and fingerprints are all as accurate as possible so that the identity of the offender and their DNA can be confirmed.

A DNA profile cannot be entered into the database if the identity of who the sample belongs to is unknown.

Here are examples of poor prints. 

If you press too hard, the print will be smudged and you will not be able to see the fingerprint ridges. Please note that a wet print can occur if the offender has recently applied lotion.

If the prints look poor, you may print the offender again.  You may put as many fingerprints as needed on the back of the card. You can print palm prints as well. If there is a reason that the offender’s prints are poor, please write it on the card; e.g., psoriasis.
