Poisonings (Intoxications): Test and Diagnosis

Laboratory parameters of the 1st order – obligatory laboratory tests.

  • Small blood count
  • Fasting glucose (fasting blood glucose)
  • Blood gas analysis (ABG)
    • If necessary, incl. determination of the carboxyhemoglobin (CO hemoglobin, CO-Hb) or methemoglobin (MetHb) value – if carbon monoxide poisoning (CO poisoning) is suspected.
  • Liver parameters – alanine aminotransferase (ALT, GPT), aspartate aminotransferase (AST, GOT), glutamate dehydrogenase (GLDH) and gamma-glutamyl transferase (gamma-GT, GGT), alkaline phosphatase, bilirubin.
  • Renal parameters – urea, creatinine, cystatin C or creatinine clearance, if necessary.
  • Coagulation parameters – PTT, Quick
  • Muscle parameters – creatinine kinase (CK), myoglobin.
  • Urine drug screening (amphetamine, methamphetamine, barbiturates, benzodiazepines, cannabis (tetrahydrocannabinol), ecstasy (methylenedioxymethylamphetamine), cocaine, methadone, morphine, phencyclidine and TCA).
  • Ethanol level
  • Drug level
  • Examination of toxic residues, food residues, etc.
  • Toxicological testing (blood, urine, vomit, evidence, respiratory gas, gastric lavage fluid, hair, fingernails and toenails).
  • MicroRNA-122 (miR-122), high mobility group box-1 (HMGB1), keratin-18 (K18) – predictors of paracetamol-associated liver injury (hepatotoxicity) [if positive → acetylcysteine (ACC) by i.v. infusion).
  • Pregnancy test (quantitative HCG).

Urine and blood/serum samples should be collected as soon as possible and forwarded for laboratory diagnosis!
