Anti-Histone Antibodies (Anti-Histone)
Autoantibodies directed against core histone proteins (H1, H2A, H2B, H3, H4) complexed within nuclear nucleosomes.
Standard vs. Optimal Reference RangesUnits
Standard reference intervals represent the statistical 95% distribution of unselected commercial populations. Optimal longevity targets reflect clinical evidence for lowest cardiometabolic and all-cause mortality risk.
Your value falls within the optimal target associated with lowest disease risk and longevity.
<1.0 U (negative)
General reference distribution across unselected commercial populations.
<0.5 U
Concentration target associated with minimal all-cause cardiometabolic mortality.
Molecular Mechanism & Clinical Purpose
Triggered by pharmacological agents that undergo slow hepatic N-acetylation (Hydralazine, Procainamide, Isoniazid, Minocycline), inducing nucleosomal neoepitopes.
Differential Diagnosis
Elevated Levels (Anti-Histone High)
- •Drug-Induced Lupus Erythematosus (DILE, Procainamide, Hydralazine, anti-TNF)
- •Systemic Lupus Erythematosus (idiopathic)
Low Levels (Anti-Histone Low)
- •Resolution of drug-induced autoimmunity after medication cessation
- •Healthy baseline

Pre-Analytical Caveats & Diagnostic Workup
Pre-Analytical Considerations:
Specimen collection should follow standardized phlebotomy protocols. Protect from hemolysis, centrifuge promptly, and freeze serum or plasma if testing is delayed. Patient should be in a resting, fasting state where indicated.
Reflexive Testing Protocol:
- Confirmatory testing and secondary biomarker quantification for Anti-Histone
- Targeted organ system imaging or functional dynamic testing related to drug-induced lupus erythematosus
- Comprehensive baseline metabolic, renal, and inflammatory assessment (CMP, CBC, hs-CRP)
