Anyone had pharmacogenetics testing (not pharmacokinetics)?

Pharmacogenetics defines the relative strength of the enzymes that break down any drugs you're taking. The stronger the enzyme, the faster the drug is broken down, and the faster the drug is cleared from your system. If a drug is broken down too quickly, it is not available to treat your neuropathy. If an enzyme is too weak or slow, the drug may accumulate causing toxicity effects, possibly making neuropathy worse. (Pharmacokinetics is different; it relates to when, ON AVERAGE, a drug peaks and is removed from system - NOT tailored to the individual.)
