BARBITURATES - QUANTITATIVE; SERUM

The BARBITURATES - QUANTITATIVE; SERUM test measures the concentration of barbiturate compounds in a patient’s blood serum using quantitative laboratory methods (eg, immunoassay confirmed by GC-MS or LC-MS/MS). It provides an exact numeric result rather than a simple positive/negative screen, allowing clinicians to assess therapeutic drug levels, confirm suspected overdose, or evaluate recent exposure.

This test is used for therapeutic drug monitoring (eg, phenobarbital therapy for epilepsy), toxicology in emergency settings, and compliance checks in substance-use or pain-management programs. Results should be interpreted alongside clinical findings and medication timing; abnormal values are reviewed by a physician to guide treatment, dose adjustment, or further toxicology workup in Dubai and across the UAE.
