Part Descriptions
LP16198-1 Methotrexate
High-dose methotrexate (MTX) is an antimetabolite drug used in treatment of cancer, and low-dose methotrexate (MTX) is used as a disease modifying antirheumatic drug (DMARD) for long-term treatment of rheumatoid arthritis (RA), psoriasis, and other autoimmune diseases. Methotrexate is a first-line drug in RA treatment. One challenge in the use of the drug is that about 30% of patients do not respond to treatment or experience adverse effects, such as gastrointestinal symptoms, malaise, and psychological complaints.

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 In contrast to "Body fld", the System "Asp" in LOINC represents the fluid withdrawn during an aspiration procedure from an abnormal collection of fluid, such as from an abscess or cyst.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.
