Access All ClinLab Navigator Information On the Go

Laboratory testing affects persons in every stage of life, and almost everyone will have numerous laboratory tests during their lifetime. More than 4000 different laboratory tests have been developed, of which, approximately 500 are ordered on a daily basis. Laboratory test results comprise about 70 percent of the average patient's medical record. Up to 85 percent of decisions about diagnosis and treatment are based on laboratory results.  

Today physicians, other health care workers and patients are finding it increasingly difficult to keep up with the tremendous amount of information being generated by clinical laboratories.
