According to research, psychotropic medications, including antidepressants, are among the common drugs that can interfere with laboratory test results. The potential impacts range from altering specific physiological markers to causing false positives on screening tests. Understanding how and why antidepressants can affect blood test results is crucial for both patients and healthcare providers to ensure accurate interpretation and proper clinical decisions.
