Enhanced DNA Blood Sample Collection Card Kit (FTA DNA Card)

Description

The Enhanced DNA Blood Sample Collection Card Kit (Dual-Spot Version) is designed for DNA testing, forensic sampling, and DNA database operations. Each kit contains a dual-spot DNA collection card (FTA card), one sterile blood lancet, one dry cotton swab, one alcohol swab, and one protective archive bag, packaged 50 kits per box. The collection card undergoes specialized treatment and sterilization to prevent external contamination. Single-sample design avoids cross-contamination, while integrated disposable sampling tools enable easy, standardized blood collection from live subjects, scene samples, or cadavers. The dual-spot card allows multiple analyses from a single collection. The protective membrane prevents liquid seepage, maintaining DNA stability and allowing safe room-temperature storage. All pathogenic agents are inactivated on the card, ensuring operator safety during handling, transport, and storage.

Usage Instructions:

1. Collect sample: For live peripheral blood, apply or drop blood onto the dual-spot card. For scene or cadaver samples, spread blood with a lancet or swab. Follow integrated card instructions if included.

2. Drying: Allow card to dry naturally in a ventilated, cool area; do not seal in plastic while wet.

3. DNA analysis: Extract individual spots using tweezers or scissors; each spot ensures high-quality DNA testing.

4. Record information: Write subject and sample data directly on the card or archive bag.
