Xylitol is safe for humans, but is EXTREMELY toxic to dogs. Even small amounts of xylitol can result in hypoglycemia, seizures, liver failure, or even death in dogs. Symptoms of xylitol consumption appear within 15-30 minutes of consumption, and include vomiting, lethargy, incoordination, termors, seizures, and coma.

The TPMT lab test, or the Thiopurine methyltransferase test, is a blood test used to check levels of the enzyme thiopurine before beginning certain therapies.This test can indicate whether or not thiopurine drugs will be an effective and safe treatment for the patient.slide 1 of 6.

A small number of people are deficient in the TPMT enzyme needed to metabolize these drugs. This can result in serious toxicity. Testing TPMT levels before starting the drug therapy can prevent it. slide 1 of 5. Thiopurine methyltransferase (TPMT) is an enzyme whose physiological function is not well understood. small but significant portion of the population is TPMT-deficient. Low TMPT levels can result in thiopurine drugs being inadequately metabolized. This can lead to life-threatening toxicity as the un-metabolized drug accumulates in bone marrow.
