Retroperitoneal Mass: Test and Diagnosis

1st order laboratory parameters – obligatory laboratory tests.

  • Small blood count
  • Differential blood count
  • Inflammatory parameters – CRP (C-reactive protein) or ESR (erythrocyte sedimentation rate).
  • Urine status (rapid test for: pH, leukocytes, nitrite, protein, glucose, ketone, urobilinogen, bilirubin, blood), sediment, if necessary urine culture (pathogen detection and resistogram, that is, testing suitable antibiotics for sensitivity / resistance).
  • 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.
  • Β-HCG (β-subunit of human chorionic gonadotropin), α-fetoprotein (AFP) – if testicular carcinoma (testicular cancer) is suspected.
  • Ascites examination after paracentesis (draining fluid from the abdominal cavity) – in the presence of ascites.
