Methanol test

What the risks are:

Collection of blood may be associated with:

  • excessive bleeding
  • fainting or feeling lightheaded
  • hematoma (blood accumulating under the skin)
  • infection (a slight risk any time the skin is broken)
  • multiple punctures to locate veins


Special considerations:

Oddly enough, the treatment for methanol poisoning is intravenous (directly into a vein) infusion of grain alcohol (ethanol). Because ethanol is broken down by the same  enzyme in the liver that converts methanol to formaldehyde, adding ethanol to the blood stream slows down the production of formaldehyde to a rate at which the body can dispose of it in the urine or through other less common chemical reactions.

Veins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.
