Reference range

Reference values are dependent on the specific body fluid type (e.g., cerebrospinal fluid, pleural fluid, peritoneal fluid, pericardial fluid, synovial fluid) and clinical context. B-lymphocyte subsets in body fluids are generally interpreted in conjunction with peripheral blood counts and clinical findings. Consult laboratory-specific reference ranges for the specific fluid type analyzed.N/A

标本类型: serum

No special patient preparation required. The specific body fluid must be collected by an appropriately trained healthcare professional using aseptic technique appropriate for the fluid type (e.g., lumbar puncture for CSF, thoracentesis for pleural fluid).

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
