Day(s) Test Set Up

Monday-Friday

Test Classification and CPT Coding

86038-ANA

83516-Ribosome Antibodies (if appropriate)

86225-Double Stranded DNA antibodies (if appropriate)

86235-Extractable Nuclear Antigen Screen (if appropriate)

 

Useful For

Evaluating patients suspected of having a systemic rheumatic disease.

Specimen Collection

Draw blood in a serum gel tube.  Spin down and send a mimimum of 1 mL serum refrigerated.  Specimens that will not reach the laboratory within 48 hours must be frozen.

 

Unspun specimens must be transported at ambient temperature and arrive at the laboratory within 1 hour of collection.

Testing Algorithm

If antinuclear antibodies are > 20 U, then antibodies to double stranded DNA, extractable nuclear antigen screen, and ribosome  are perfomred at an extra charge.

 

If extractable nuclear antigen screen is positive, the sample will be sent to Mayo for differentiation at an additional charge.
