Blood Sample Collection Kit Procedures
Please carefully read and follow the directions provided or else the sample could be
rejected and require a recollection. Blood samples may be rejected for a number of reasons, including:
- The seal on the outside of the kit box is missing. The seal is very important because it
indicates that no tampering has occurred to the sample envelope.
- The blood collection tube is less than ¼ full. You may send more than
one tube if necessary, provided they are all labeled.
- The blood tube is not labeled. All blood tubes MUST be labeled.
- The blood tube is not a purple top or has expired.
- The blood tube is labeled differently than the fingerprint card. The label
on the blood tube MUST match the information contained on the fingerprint card.
- 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 be rejected.
NOTE: It is preferable that the offender sign the fingerprint card; however,
this is not required. If the offender refused to sign the card, send the
IMPORTANT: Blood collection must be performed only by a physician, nurse,
or licensed clinical lab technologist.
To complete a blood sample collection kit, perform the following procedures on ONE subject
at a time
- Fill out the DNA blood database card (LAB-13) with the subject’s identifying
information on lines 1 through 5.
- Remove components from the kit box and lay them out.
- Cleanse the blood collection site with the prep pad provided. Following normal
medical procedures and using the needle and blood tube provided, withdraw
the blood specimen from the subject, allowing the tube to fill to maximum
volume. If necessary, a smaller gage needle may be substituted.
- Print the subject’s full name, DOB and/or SID number on the blood tube
- Immediately after blood collection, assure proper mixing of
anticoagulant by slowly and completely inverting the blood tube at least five
times. DO NOT SHAKE VIGOROUSLY.

the kit box. Discard using recommended OSHA procedures.
DO NOT remove the liquid absorbing sheet from the Ziploc bag.
- Fill out the information requested on lines 8 (if known), 9, and 10 of the
LAB-13. Either type or print clearly and neatly all remaining information
requested on the LAB-13. Have the subject sign on line 6. Then, using
normal fingerprint procedures, fingerprint the subject’s left and right
thumb where indicated on the card (section 7).
- Check the identifying information on the blood tube label and compare it with
the information on the LAB-13 to verify that the information matches and
- Insert the filled blood collection tube into the bubble pack blood tube protector,
then seal the blood tube protector using the self-stick adhesive strip.

Ziplock bag, then squeeze out excess air and close the bag.
