Document Summary
Laboratory tests should be ordered to assist with making a decision regarding the management of a patient rather than to satisfy a curiosity". Always interpret laboratory tests relative to the actual patient. Rule in or rule out a specific diagnosis: monitor for desired effect or adverse effect. Factors that occur in the analysis of specimen. Not all test results outside of the range are abnormal or problematic. May prompt the need for further testing. Need to be interpreted relative to baseline values, patient-specific condition, and any therapy the patient is receiving. Test results that fall within the range may still be of concern. Reference range is typically defined as the mean value 2 standard deviations (sd), which captures roughly 95% of the sample population. <4. 0 mmol/l is the treatment target level for high risk patients. <5. 5 mmol/l is the ideal level in normal risk patients. <5. 4mmol/l for children <18 years old puts them within 95th percentile.
