Why should a laboratory report form indicate the fact that specimen has been collected by capillary puncture?

A laboratory report form should indicate that a specimen has been collected by capillary puncture to ensure proper interpretation of the results, as capillary blood can differ in composition from venous blood. This distinction is crucial for accurate diagnosis and treatment, as certain tests may have different reference ranges or may be affected by the method of collection. Additionally, it helps laboratory personnel apply appropriate handling procedures and quality control measures specific to capillary specimens.
