2nd order laboratory parameters – depending on the results of the history, physical examination and obligatory laboratory parameters – for differential diagnostic clarification.
- Small blood count [alcohol dependence: MCV ↑]
- Differential blood count
- Inflammatory parameters – CRP (C-reactive protein) or ESR (erythrocyte sedimentation rate).
- Fasting glucose (fasting blood glucose).
- Thyroid parameters – TSH
- Blood smear if malaria or other infectious diseases are suspected.
- Serological tests – if bacterial, viral or parasitic diseases are suspected.
- Interferon-gamma release assay (synonyms: γ-interferon test; English interferon-gamma release assay, IGRA) – for suspected tuberculosis [specificity (probability that actually healthy people who do not suffer from the disease in question are also detected as healthy in the test) for the detection of latent tuberculosis is higher than for the tuberculin skin test; the test result is not affected by a previous BCG vaccination]
- Autoantibody addiction tests
- Tumor markers – depending on the suspected diagnosis.
- FSH, 17-beta estradiol – to exclude menopause.
- Testosterone – to exclude andropause.
- Carbodeficient transferrin (CDT) [CDT ↑ in chronic alcoholism]
- Antibodies in suspected autoimmune diseases such as ANA (antinuclear antibodies).
- Drug test
