How Accurate Is A Urine And Blood Toxicology Test?
Depends on liver health
Detailed Answer:
Hi
I am Dr Mittal
The medicines you have mentioned are detoxified and excreted by the liver.
Liver is a very powerful organ unless the dose of the medicine is too high.
So unless the dose of the medicine overcomes the detoxification capability of the individual, the toxicity will not happen, and therefore may not show.
The capability of the liver depends on circumstances and person to person depending on things like alcohol abuse and hepatitis and other such factors that affect the liver health in general.
If however, the liver is overcome, blood tests may show the drug levels that may show toxicity.
as for hair follicle test, it is usually more common for heavy metal poisoning like lead and arsenic.
I hope that explains the idea to you.
Please feel free to contact me for further advice.
