Thanks for your query.

Important aspects of your query are:
•     48 year old female.
•     Known case of Chronic back pain.
•     History of Amitriptyline use 10 weeks back.
•     Concern related to Amitriptyline detection in blood.

Amitriptyline is a tricyclic group anti depressant. It is used for chronic pain disorder and depression. Its level in body is done by blood testing specially to maintain adequate serum level of drug.

It is primarily metabolised by liver and excreted through kidney. Its half in body is 10–50 hours, with an average of 15 hours. It is washed away from body in 1-2 week of stoppage.
