Understanding Lab Tests for Alcoholism and Drug Abuse
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Alcoholism and drug abuse are complex behavioral health conditions that are typically diagnosed through clinical evaluation, medical history, and behavioral assessments. While there isn't a single blood test that can definitively diagnose substance abuse disorders, laboratory testing plays a crucial role in detecting physical complications and organ damage that can result from chronic alcohol and drug use.
Recommended Test
Creatine Kinase (CK), Total, Serum
This test measures the level of creatine kinase, an enzyme found in muscle tissue. Chronic alcoholism and certain drugs of abuse can cause significant muscle damage and breakdown. Elevated CK levels in the blood indicate muscle injury and help healthcare providers assess the extent of muscle damage and monitor recovery progress.

Why Blood Testing is Important in Substance Abuse Cases
Chronic alcohol consumption and drug abuse can cause significant damage to various organs and body systems, including the liver, heart, kidneys, and muscles. Blood tests are fundamental for assessing the extent of this damage, monitoring organ function, and guiding treatment decisions to prevent further complications and support recovery.
Understanding the Role of Laboratory Testing
Laboratory testing in the context of substance abuse serves multiple purposes: detecting acute intoxication through specific substance screening, evaluating organ damage from chronic use, monitoring nutritional deficiencies, and tracking recovery progress. These tests provide objective medical data that complement clinical assessment and help healthcare providers develop comprehensive treatment plans.
