| Immunoelectrophoresis, serum and urine (087-0242) | |
|---|---|
| Test Mnemonic: | IEP SER+UR |
| Specimen Requirements: | |
| Test Included: | Serum: Total Protein, Albumin, IgG, IgA, IgM, High Resolution electrophoresis, Interpretation and immunofixation as needed. Urine: Qualitative Protein, High Resolution Electrophoresis, interpretation and Immunofixation as needed. |
| Collection: | Routine venipuncture and 24 hour urine collection or random urine. |
| Container: | Routine venipuncture: 7 mL of blood in SST (gel barrier) preferred; red-topped tube acceptable (Min.: 3mL). Urine: 10 mL random urine specimen collected in a sterile evacuated urine specimen tube or container with no preservative. |

| When ordering tests for which Medicare or Medicaid reimbursement will be sought, physicians should only order tests that are medically necessary for the diagnosis or treatment of the patient. Components of the organ or disease panels may be ordered individually. The diagnostic information must substantiate all tests ordered and must be in the form of an ICD-10 code or its verbal equivalent. | |
