|Methodology||Indirect Immunofluorescence / Turbidimetric Immunoassay / Electrophoresis / Immunofixation|
|Description||Useful for the overall assessment of a patient's protein status; often utilized if autoimmune, lymphoproliferative, or immunodeficiency disorders are suspected.
NOTE: Tests may be ordered individually.
NOTE: This test, when ordered on Medicare patients, is subject to the National Coverage Determination (NCD) policy "Serum Iron Studies". Please verify that the diagnosis code (ICD-9) you have chosen demonstrates medical necessity for the test as documented in the physician's patient record. The CMS web site or the NorDx Limited Coverage Documentation Guide are available to assist you with this verification. A properly executed Advance Beneficiary Notice (ABN) must be submitted with the specimen if medical necessity is not demonstrated by the ICD-9 code chosen or if the frequency of a frequency-limited test is unknown.
NOTE: This test is usually ordered in conjunction with a pathology consultation. The pathology professional component will be billed separately.
