Interpretation

Amniotic: Amniotic fluid glucose concentrations < 10 mg/dL are consistent with intra-amniotic inflammation in patients with prelabor rupture of membranes. 

 

Peritoneal: Peritoneal glucose concentrations >50 mg/dL (2.8 mmol/L) are consistent with spontaneous bacterial peritonitis and concentrations below this are consistent with secondary bacterial peritonitis due to gut perforation.

 

Pericardial: Pericardial fluid glucose to serum/plasma glucose ratios are 1.0 in presumed 'normal' patients. 

 

Pancreatic Body Cyst: Pancreatic Cyst Glucose measurements of ≤ 50 mg/dL are suggestive of a mucinous lesion. 

 

Pleural: Pleural fluid glucose concentrations are equivalent to serum/plasma glucose concentrations in the absence of pleural pathology. Pleural fluid glucose concentrations < 60 mg/dL may indicate parapneumonic or malignant effusion. Other less common effusions associated with low glucose concentrations include hemothorax, tuberculosis, rheumatoid pleuritis, Churg-Strauss syndrome, paragonimiasis, and lupus pleuritis.

 

Synovial: Synovial fluid glucose concentrations lower than glucose in serum/plasma are associated with infection.

Method Description

Photometric rate with hexokinase
