Available as global test only for bronchoalveolar lavage (BAL) specimens. Markers are CD3, CD4, CD8, and CD45 (4 markers). This test is not for quantitative immune status monitoring. (Tech-only testing is not offered as this test does not have a separate professional component.)
This panel can be helpful to differentiate sarcoidosis and hypersensitivity pneumonitis from other causes or types of interstitial lung disease.

Please send specimens as soon as possible after collection. Ideally specimens should be received at NeoGenomics within 24 hours from collection for optimal sample integrity and acceptable cell viability. Refrigerate specimen. Do not freeze. Use cold pack for transport, making sure cold pack is not in direct contact with specimen.
