Peritoneal fluid(Ascitic fluid)
Synovial fluid
Pleural fluid
Pericardial fluid
Sputum
1 ) pH – measured by pH paper
2) Color - crystal clear and colorless
Ependymal cell
– RBC count
– WBC count
– differential count
– Estimation of glucose
– Estimation of LDH
Estimation of glucose-
decreased in peritonitis ,malignancy
Estimation of amylase
Increased in acute pancreatitis
Estimation of ALP
Elevated in intestinal perforation

PERICARDIAL FLUID
• About 10-50 ml of fluid is normally present in the
pericardial space
• Accumulation of excess fluid- pericardial effusion
• Fluid is obtained by aspiration using a sterile
needle under aseptic condition called
pericardiocentesis
• PHYSICAL EXAMINATION
Color: straw colored clear normally
Cloudy/turbid: septic condition, chronic effusion
Blood tinged: traumatic tap
Milky effusion : TB ,leakage from thoracic duct.

• MICROSCPIC EXAMINATION
Increased leukocyte (>1000/cumm) with a
predominant of polymorphs suggests bacterial
pericarditis
Predominance of lymphocytes indicate
tuberculous or viral pericarditis
Eosinophilia of pericardial fluid is rare.
• PHYSICAL FINDINGS
– Volume
– Appearance
• MICOSCOPICAL EXAMINATION
– Total count
– Differential count
