Toxicology is a field of science that investigates the biological effects of dangerous substances. It is commonly associated with drug testing and because of popular media, forensic autopsy reports.


Histopathology Services provides clinical toxicology testing for drugs and their metabolites principally in urine. Qualitative and quantitative testing is performed. Enzyme Immunoassay (EIA) is a Biochemical Methodology that identifies the presence of Drugs and /or drug metabolites and Liquid Chromatography-Mass Spectrometry allows for a more accurate picture of a Patient’s toxicological profile.

Why Request Testing

One of the many concerns in pain management is the identification of patients that have aberrant, drug-related behavior or other similar conditions. To address this, it is important that physicians ask their patients to undergo a drug test.

An important reason for requesting drug testing is to protect the physician from prescribing medication that could be harmful if taken with other medicine the patient may be taking. This reduces doctor liability should something go wrong.

The patients should always be prioritized and having them tested can lead to a higher standard of care. Not only does it provide a better outcome, but it also ensures patient compliance. This allows us to see if individuals are misusing or abusing the readily available pain management drugs.
