Laboratory parameters of the 1st order – obligatory laboratory tests.
- Electrolytes – calcium* , magnesium, sodium, potassium.
- Fasting glucose (fasting blood sugar)
- Thyroid parameters – TSH
- 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.
- Creatine kinase (CK)
* Rarely hypocalcemia (calcium deficiency) with blood Ca < 2.25 mmol/l = < 9 mg/dl = < 4.5 mval/l, usually normocalcemic forms of tetany are present.
2nd order laboratory parameters – depending on the results of the history, physical examination and obligatory laboratory parameters – for differential diagnostic clarification
- Cortisol
- Aldosterone
- Parathyroid hormone
- Vitamin D
- Serum lactate
- CSF puncture (collection of cerebrospinal fluid by puncture of the spinal canal) for CSF diagnosis.
