Discover how temperature-controlled vacuum transport bags prevent sample degradation during doorstep home blood pickup.
Blood samples are sensitive biological specimens. Exposure to heat or agitation during transport can cause hemolysis or enzyme breakdown. At Diagnostics Wala, phlebotomists collect samples in vacuum sealed tubes and transport them in 2-8°C cold-chain insulated bags directly to NABL labs.
