Buccal Swab Sample Collection Kit Procedures
Please carefully read and follow the directions provided in the sampe envelope
or else the sample could be rejected and require a recollection. Recollections
of mouth swab samples can be frequent if the procedures are not done
swab samples could be rejected for a number of reasons, including:
- The seal on the outside of the envelope is missing. The seal is very important
because it indicates that no tampering has occurred to
the sample envelope.
- The mouth swab samples are moldy. To help prevent the samples from growing
mold, please be sure to let the swabs dry for at least
five minutes before sealing them in the swab envelope. Do not put the swab
back into its original plastic sleeve.
- The swab envelope is not labeled. All swab envelopes MUST be labeled.
- The swab envelope is labeled differently than the fingerprint card. The
name and SID number on the envelope must match the information on the fingerprint
card. Please include both pieces of information (when available) on
the swab envelope.
- The fingerprints are missing from the fingerprint card. Also, be aware
that the fingerprints on the card will be verified by
DPS. As a result, if the card provides prints from only the tips of the fingers,
or if the prints are too light, smeared, or unreadable, then the sample will
- Not enough information is included on the card. Put all available
information on the card, including name, DOB, identifying
numbers (SID, TDC, TYC, Social Security, FBI, or any
other number that can help lab personnel identify the
subject), offense for which they are being sampled, where the offender
is located (which agency is having him/her sampled; please
do not abbreviate), phone number of the agency that is
having the offender sampled, and the date the sample
NOTE: It is preferable that the offender sign the fingerprint card; however,
it is not required. If the offender refuses to sign the card, send the sample anyway.
IMPORTANT: The subject should have no food or drink for 20 minutes
prior to having the sample taken.
