Lab tests can efficiently and accurately measure health parameters such as electrolytes, hormones, enzymes, proteins and other indicators to diagnose patient conditions or monitor treatment progress. Lab testing is essential for patient care management.

Laboratory medicine plays a crucial role in drug therapy management by providing objective evidence of the presence of drugs or their metabolites in blood, urine or tissue samples. This helps clinicians monitor drug levels to ensure efficacy and safety, prevent adverse side effects from overdosing or underdosing, reduce risks of drug interactions with current medications and provide information on compliance with prescribed regimens. Clinical laboratory professionals play an important role in interpreting test results and making recommendations about medication dosages based on those results. Lab tests also help detect drug abuse and misuse that may require treatment.
