The medical logistics industry is full of round, attention-grabbing numbers about how much laboratory errors cost healthcare systems. We think our clients deserve better than that. Here is what the actual peer-reviewed research shows — with full citations.
What the Research Measures: The Pre-Analytical Phase
Up to 70% of laboratory errors occur in the pre-analytical phase — before a sample ever reaches the analyzer. This phase includes test ordering, patient preparation, specimen collection, labelling, handling, and transport. It is the phase where logistics makes a difference. The landmark figure comes from Plebani M & Carraro P, Clinical Chemistry, 1997;43(8):1348–1351, confirmed in a ten-year follow-up study by the same authors.
The Ontario Evidence: Sunnybrook Health Sciences Centre
A study directly relevant to our market examined pre-analytical errors at Sunnybrook Health Sciences Centre in Toronto — one of Canada's leading academic health sciences centres. Across 557,411 INR test requests, 13.1% carried a pre-analytical error code. Investigating and documenting those errors cost the hospital USD $39,939 per year — representing 10.5% of the hospital's entire annual INR testing budget.
This is a precise, verifiable number from a peer-reviewed study conducted right here in Ontario. It does not cover the full cost of repeated draws, delayed diagnoses, or extended hospital stays — but it is real, checkable, and an honest representation of what pre-analytical errors cost at the point of laboratory management alone.

- Setting: Sunnybrook Health Sciences Centre, Toronto, Ontario.
- Finding: 13.1% error rate; USD $39,939/year in investigation costs; 10.5% of INR testing budget.
The Alberta Evidence: Unnecessary Repeat Testing
A separate Canadian study measured the cost of clinically unnecessary repeat testing — a different but related problem. In Alberta, unnecessary repeat complete blood count (CBC) and electrolyte panel tests cost the provincial system approximately CAD $2.4M per year combined. This is not a measurement of transport or handling errors — it captures the downstream cost of repeating tests that should not have been re-ordered — but it illustrates the scale of waste that poor specimen handling can contribute to when a viable sample is not delivered first time.
- Study: Kandalam V et al. "Inappropriate repeat testing of complete blood count and electrolyte panels in inpatients from Alberta, Canada." Clinical Biochemistry. 2020;77:32–35.
- Setting: Province-wide, Alberta, Canada.
- Finding: CAD $2.4M/year in unnecessary repeat CBC and electrolyte testing costs.
What This Means for Your Institution
The numbers above are modest compared to the marketing claims you may see elsewhere — and that is precisely the point. They are real, checkable, and represent a minimum floor rather than a ceiling. Pre-analytical errors generate costs that show up across re-collection, extended lab turnaround, delayed clinical decisions, and patient inconvenience. A reliable logistics partner with documented cold-chain integrity and chain-of-custody records helps eliminate the preventable failures at the transport and handling stage.
