A proposal for laboratory data reporting.

Changes are proposed regarding the presentation of laboratory information. More definitive statements are required for reference limits, sampling variance (the Clinical Delta Range), and multivariate group analysis of large test batteries. To make this transition possible, laboratory reports should be classed so that the practicing physician has some measure of confidence in the product and its compatability with other sources. The proposal extends to the range of financial reimbursement and suggests that class standing be issued by an accrediting agency and support a structured level of payment.
