Myocardial Antibody, IgG with Reflex to Titer : 0050742

Mnemonic: MYO R

Methodology: Semi-Quantitative Indirect Fluorescent Antibody
Performed: Mon-Fri
Reported: 1-4 days
Specimen Required: Collect: Serum separator tube.

Specimen Preparation: Separate serum from cells ASAP or within 2 hours of collection. Transfer 1 mL serum to an ARUP Standard Transport Tube. (Min: 0.15 mL)

Storage/Transport Temperature: Refrigerated.

Unacceptable Conditions: Plasma. Contaminated, hemolyzed, or severely lipemic specimens.

Stability (collection to initiation of testing): After separation from cells: Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 year (avoid repeated freeze/thaw cycles)
Reference Interval:
< 1:20 No antibody detection
Note: Myocardial antibodies are present following myocardial infarction (28-31%), acute rheumatic fever (25-43%) and in post-pericardiotomy syndrome.  All positives are titered to endpoint. If Myocardial Ab is 1:20, then a titer will be added. Additional charges apply.
CPT Code(s): 86255 Myocardial; if reflexed, add 86256 Myocardial titer
