This lesson explains the general framework. Verify the rules and requirements that apply to your state, employer, laboratory, payer, insurance arrangement and service model.
The seven stages
A technically successful blood draw can still become a failed appointment if the specimen is mislabeled, mishandled, delayed, overheated, frozen when it should not be, or delivered to the wrong place.
Verify before collection
Confirm test, tube, labeling, timing, fasting, processing, temperature and destination requirements before you leave. Every one of these is cheaper to check now than to discover at the lab counter.
Label correctly
Use the receiving laboratory's required identifiers and process. Avoid handwritten shortcuts that conflict with policy — a label that does not match the requisition is a rejection waiting to happen.
Process only when required and permitted
Centrifugation, aliquoting or other preparation should follow the specific laboratory and test workflow, and stay inside the scope your business is permitted and trained to perform.
Protect temperature and time
Different specimens have different stability requirements. Do not apply one blanket temperature rule to every tube — the cooler that protects one analyte destroys another.
Package for the actual classification
PHMSA distinguishes Category A, Category B and excepted or non-regulated materials. Classification is the shipper's responsibility, based on the material and the circumstances.
Use Category B packaging when it applies
For material properly classified as Biological substance, Category B, PHMSA guidance describes a leakproof and siftproof primary receptacle, leakproof and siftproof secondary packaging, absorbent material for liquids and a rigid outer package, with required markings and other conditions.
Document delivery
Use a clear destination, time and proof-of-delivery process, particularly when multiple labs or couriers are involved. Without it, a missing specimen becomes an argument rather than an investigation.
Transport classification
Do not label every routine tube UN3373 automatically.
Over-labeling is not the safe default it appears to be. Marking a package as hazardous when it is not carries its own consequences, and classification remains the shipper's responsibility based on the actual material and circumstances.
Common mistakes
Five patterns that turn a completed collection into a recollection, a complaint or a compliance problem.
- Using one universal handling rule for every specimen
- Assuming all patient specimens are UN3373
- Improvising specialty-kit instructions
- Leaving specimens in an uncontrolled vehicle
- Having no proof of delivery
Where XpediPro fits
XpediPro can help organize appointment and delivery status, but laboratory instructions and hazardous-material classification still require the correct operational process outside the software. The system records what happened; it does not decide what the rules are.

FAQs
Are all blood tubes Category B?
No. Classification depends on whether the material meets the hazardous-material definition and on the circumstances of transport. Do not mark packages as hazardous when they are not.
Can I use a cooler for everything?
No. Temperature requirements are test-specific, and some analytes are damaged by cooling. Follow the receiving laboratory's instructions for each test rather than applying one habit to every tube.
