Frequently Asked Questions
Who is DMLI for?
DMLI is a doctoral-level credential for PhD or MD/DO clinical laboratory immunologists. Eligibility requires completion of a CPEP-approved (Committee on Postgraduate Educational Programs) immunology fellowship program. The credential is CMS-approved as a qualification for CLIA high-complexity laboratory director, particularly in immunology specialty labs.
What ANA patterns should I master?
On HEp-2 IFA: homogeneous (anti-dsDNA — SLE; anti-histone — drug-induced lupus); speckled (anti-SSA/SSB — Sjögren's, neonatal lupus; anti-Sm — SLE specific; anti-RNP — MCTD); nucleolar (scleroderma); centromere (limited scleroderma/CREST); cytoplasmic (Jo-1 — myositis/antisynthetase; ribosomal P — SLE psychosis); nuclear dense fine speckled DFS70 (often benign in healthy individuals).
What is HLA crossmatching for transplant?
Multiple methods: (1) CDC (complement-dependent cytotoxicity) crossmatch — donor lymphocytes + recipient serum + complement; lysis indicates donor-specific antibodies. (2) Flow crossmatch — donor cells + recipient serum + secondary anti-IgG; more sensitive than CDC. (3) Virtual crossmatch — uses Luminex single antigen bead (SAB) panel to identify recipient anti-HLA antibodies + known donor HLA typing; predicts crossmatch result without physical sample mixing.
How should I study for ASCP DMLI?
Plan 120-160 hours over 16-20 weeks. Focus on Autoimmunity & CTD (20%), then Innate/Adaptive Immunity (15%), Immunodeficiency (15%). Master ANA pattern → autoantibody → disease association mapping; primary immunodeficiency workup (TREC, CGD/DHR, IgG/IgA/IgM quant, vaccine response); HLA typing and crossmatch methods; ACMG/AMP variant classification when applicable to immunogenetics.
