Deaths from drug overdoses have more than tripled since 1990. Because of this disturbing trend, doctors are encouraged to screen patients who are on controlled medications to ensure their safety. TOPLAB® provides quick turnaround on drug and alcohol screenings that can help healthcare professionals prevent accidental overdoses and get their patients much needed assistance for prescription drug abuse. Making these tests routine in certain cases can help protect your patients and your practice.
