Before the White Coat

Why school science lessons provide the perfect setting to teach students to think like laboratory professionals

1

Laboratory career education should teach students that instruments generate measurements, while clinical meaning depends on interpreting them in context.
2

A precise potassium measurement from a hemolyzed specimen may not represent the patient's circulating potassium because red blood cells release intracellular potassium.
3

A result outside a reference interval is evidence to interpret, not a verdict, because reference intervals commonly include the central 95% of a specified population.
4

A positive molecular signal does not by itself establish clinical significance; interpretation may depend on the organism, specimen, timing, assay, and other evidence.
5

Students can learn laboratory reasoning by examining controls, specimen quality, analytical precision, clinical relevance, and alternative explanations, even without using a clinical analyzer.
