Poison or Toxin Testing

Unknown Substance Analysis (for an object)

An unknown substance analysis is performed on an object to identify the contents. These objects can be things such as: unknown pills, powders or other substances suspected to be a drug or an unknown stain or specimen that needs to be identified as biological or not.

Unknown Poison and Toxin Scan (for a person)

An unknown poison and toxin scan screens for and confirms the presence of unknown chemicals, poisons and toxins in a human being such as: pesticides, paints, organic exposure chemicals, painting or cleaning products, rodent poison, volatiles and inhalants. Since over 600 poison and toxin screens are available, please contact MSDT for assistance if you suspect poisoning or toxic exposure. Testing specimens may include urine, saliva, hair and nails.

Heavy Metals Exposure Tests

Certain heavy metals are essential to good health, such as selenium and magnesium. The term “heavy metals” also includes arsenic, hexavalent chromium (chromium-6), lead, cadmium and mercury, to name a few. You can get too much of a good thing, and with heavy metals, it can be toxic. Testing specimens may include urine, saliva, hair and nails.
