Why is lab testing so important in patient care?
In addition to screening for early detection, laboratory medicine also provides testing to guide treatment decisions and predict outcomes and, in some cases, to determine treatment eligibility.

I. Complete Blood Count
Complete blood count is one of the most basic laboratory examinations to assess the overall health status of a patient. It can help diagnose infections, autoimmune disorders, anemia, and other blood diseases.
II. Urinalysis
Urinalysis is usually done as part of routine diagnostic examinations. It’s a supportive tool for diagnosing illnesses. A standard urinalysis involves three stages– visual exam, dipstick test and microscopic exam.
III. Serum Electrolytes
Potassium is critical in nerve and muscle function because it communicates impulses. The movement of nutrients into the cell and the transport of waste products out of the cell are also mediated by potassium.
IV. Renal Function Tests
BUN is a by-product of protein metabolism. This test is used to determine the adequacy of renal function but it may also produce a false-positive result as it is dependent on renal blood flow, protein metabolism, catabolism, drugs, and diet.
Abstract
- Since the beginning of modern medicine, the clinical laboratory has been essential to patient care and diagnosis. However, it has been difficult to quantitatively assess the number of medical decisions that are informed by laboratory results. The longstanding claim that laboratory tests inform 70% of medical decisions was originally based on anecdo...
Materials and Methods
- The EMR was from Cerner Millennium implemented in 2004 and was expanded over several years. Now, paper records have been eliminated and the EMR includes records of all physician, nursing, and ancillary transactions that occur for a patient. In any medical system, there are many clinical decisions made that are documented by progress notes, consultation notes, nursing not…
Results
- Fig. 1shows that laboratory tests were the most frequently ordered diagnostic procedure (25334 of 72197 [35.0%] patient encounters) followed by radiology, vital signs, respiratory, cardiology, and other.
Discussion
- We observed that laboratory use varied depending on treatment areas. The greater the acuity of a patient population, the more likely the laboratory was used, which explains why almost all inpatients used laboratory testing. The illnesses in an inpatient population are typically more severe and require frequent monitoring of pathophysiologic biomarkers and therapeutic drugs a…
