      Hypertension is often primary, or essential, in which no apparent cause can be determined from the usual investigative maneuvers, such as taking a history, performing a physical examination, and screening laboratory results. In these individuals, the laboratory serves chiefly to estimate target organ damage, if present, and to identify the presence of other cardiovascular risk factors that may influence the choice of antihypertensive therapy. In other patients, the screening laboratory findings, in conjunction with the appropriate clinical setting, leads to the choice of specific diagnostic tests that elucidate the presence of a secondary cause for hypertension. This review covers the rationale for the basic screening tests and the pursuit of suspicious findings from the screening laboratory evaluation.
