LP14735-2   Tricyclic antidepressants
Tricyclic antidepressants get their name from their three ringed molecular structure. The primary use of tricyclic antidepressants is to treat depression as well as neuralgic pain, chronic pain, and migraine prophylaxis. In children, tricyclic antidepressants are used to treat enuresis, obsessive-compulsive disorder, attention deficit hyperactivity disorder, school phobia, and separation anxiety. These drugs are are taken orally and are absorbed by the liver and then excreted through the kidneys. Tricyclic antidepressants block the absorption of neurotransmitters at nerve terminals, which makes the neurotransmitters more available in the brain.

Change Reason
The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.; The EIA method, which was always intended to cover more than just enzyme-linked immunoassay and whose display name for the long common name has always been Immunoassay, was renamed IA in order to eliminate ambiguity about whether the method has a broader meaning than just enzyme-linked immunoassay. Likewise, EIA.rapid was renamed IA.rapid. These changes were approved by the Laboratory LOINC Committee in June 2016.
