Safe blood sampling procedures and sample protection guidelines are essential to safeguard personnel and ensure sample integrity across clinical, forensic, and research settings. These protocols minimize infection risks and prevent sample degradation for reliable test results.
Core Safe Sampling Procedures
-
Prep & PPE: Wash hands; wear gloves, mask, and gown. Inspect tools (syringes, vacutainers) for sterility and expiry.
-
Site Preparation: Disinfect the puncture site with 70% alcohol; allow to dry completely to avoid contamination.
-
Collection Technique: Use venipuncture/capillary method per sample type; avoid vein damage. Dispose of needles in sharps containers immediately post-use.
-
Hemostasis: Apply gentle pressure with gauze post-collection; secure with bandage to prevent bruising.
Sample Protection Guidelines
-
Preservation: Add appropriate additives (EDTA, citrate) immediately; mix gently to avoid clotting.
-
Storage: Maintain 2–8°C for short-term (24–48hrs); freeze at -20°C/-80°C for long-term storage.
-
Transport: Use insulated coolers with ice packs; avoid extreme temps and direct sunlight.
-
Labeling: Mark samples with unique ID, date, time, and collector to ensure traceability.
