Part Descriptions

LP14735-2   Tricyclic antidepressants
Tricyclic antidepressants (TCA) are a class of drugs first used in the 1950s. They are named after the drugs' molecular structure, which contains three molecular rings (compared to tetracyclic antidepressants).

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.

LP7238-1   Body fld
The LOINC "Body fld" System represents body fluids other than serum, plasma, blood, urine, and cerebrospinal fluid. When a LOINC term with the System "Body fld" is used, the specific specimen source or body fluid type should be reported elsewhere with the result. Where more specific terms for pleural, peritoneal, synovial fluid, etc. exist, we encourage you to use the more specific terms. In contrast to "Body fld", the System "Asp" in LOINC represents the fluid withdrawn during an aspiration procedure from an abnormal collection of fluid, such as from an abscess or cyst. "Asp" is used for abnormal fluid collections that are aspirated, while "Body fld" is used for named body fluids, such as synovial fluid or peritoneal fluid, that are not inherently pathologic.
