Laboratory parameters of 1st order – obligatory laboratory tests in short bowel syndrome.
- Small blood count
- Inflammatory parameters – CRP (C-reactive protein) or ESR (erythrocyte sedimentation rate).
- Urine status (rapid test for: Nitrite, protein, hemoglobin, erythrocytes, leukocytes, urobilinogen) incl. sediment, if necessary urine culture (pathogen detection and resistogram, that is, testing of suitable antibiotics for sensitivity / resistance).
- Electrolytes – calcium, potassium, sodium, magnesium, phosphate.
- Ferritin
- Fasting glucose (fasting blood glucose), if necessary oral glucose tolerance test (oGTT).
- HbA1c,
- Liver parameters – alanine aminotransferase (ALT, GPT), aspartate aminotransferase (AST, GOT), glutamate dehydrogenase (GLDH) and gamma-glutamyl transferase (gamma-GT, GGT).
- Bilirubin
- Amylase
- Renal parameters – urea, creatinine, possibly cystatin C or creatinine clearance; if necessary, also evidence of microalbuminuria.
- Uric acid
- Total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides.
- Total protein, albumin
- Quick or INR (Vit. K)
- Blood gas analysis (ABG), venous
- Vitamins – D, B12, folic acid
- Parathyroid hormone
- Trace elements – copper, selenium, zinc
- Test for occult (not visible) blood in the stool.
Laboratory parameters 2nd order – depending on the results of the history, physical examination, etc. – for differential diagnostic clarification.
- Creatinine coefficient (amount of creatinine excreted in urine in 24h/kg body mass; men: 20-26, women: 14-22) – for evaluation of nutritional status.
Note: Not all of these parameters need to be collected at each patient presentation.
