Blood sample storage and transportation in hot (＞30°C) and humid (＞60% RH) conditions demand specialized solutions to prevent degradation, hemolysis, and microbial growth. These solutions combine temperature control, moisture barriers, and preservatives to maintain sample integrity for testing.
Core Solutions
-
Insulated Containers: Use phase-change material (PCM) coolers or vacuum-insulated boxes to maintain 2–8°C for 24–72 hours; avoid ice direct contact with samples.
-
Moisture-Resistant Packaging: Seal samples in vacuum-sealed foil bags with silica gel desiccants to absorb humidity; use O-ring tubes for liquid samples.
-
Preservative Additives: Add EDTA (for hematology) or protease inhibitors (for proteins) to slow degradation; use dried blood spot cards for room-temp transport.
-
Rapid Logistics: Prioritize same-day or next-day shipping; track temperature via data loggers for real-time monitoring.
Key Features
-
Thermal Stability: Sustains target temps despite external heat fluctuations.
-
Humidity Control: Prevents moisture-induced microbial growth and sample clumping.
-
Sample Versatility: Works for liquid blood, plasma, serum, and dried blood spots.
-
Compliance: Meets IATA, WHO standards for safe transport of biological materials.
Scope & Applications
-
Tropical Clinical Settings: Transporting patient samples to central labs in hot, humid regions.
-
Field Research: Storing blood samples from wildlife or remote human populations.
-
Disaster Response: Managing blood supplies and test samples in post-storm/hurricane areas.
-
Global Health: Shipping blood samples for disease surveillance in equatorial countries.
