Sample handling and transport
Mixing, labelling, packaging and getting samples to the laboratory.
After collection
Invert each tube gently as the manufacturer instructs, check the labels against the request, and keep tubes upright in a rack or holder.
Packaging
Blood samples sent to a laboratory are usually transported as UN3373 Biological Substance, Category B, in triple packaging: the tube, a sealed leak-proof bag with absorbent material, and a rigid outer container marked UN3373. Keep request forms separate from the samples.
Timing
Each test has a stability limit, set out in the laboratory’s handbook. Plan your route so samples reach the laboratory within it.
Rejected samples
Common reasons are haemolysis, clotted samples, labelling errors, late arrival, the wrong tube, underfilling and temperature problems. Use rejection feedback to improve.
