LP16738-4   Rheumatoid factor
Rheumatoid factor (RF or RhF) is a blood test performed in patients with suspected rheumatoid arthritis (RA). It is an auto-antibody directed against the Fc portion of IgG, which is itself an antibody. RF and IgG form immune complexes, which are part of the disease process (serum sickness) of various rheumatological diseases. Storage/Transport Temperature: 1 mL plasma or serum, 2-8°C. (Min: 0.2 mL) Submit specimen in an ARUP Amber Transport Tube. Rheumatoid factor can also be a cryoglobulin (antibody that precipitates on cooling of a blood sample); it can be either type 2 (monoclonal IgM to polyclonal IgG) or 3 (polyclonal IgM to polyclonal IgG) cryoglobulin.

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 In contrast to "Body fld", the System "Asp" in LOINC represents the fluid withdrawn during an aspiration procedure from an abnormal collection of fluid, such as from an abscess or cyst.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