How is familial chylomicronemia syndrome (FCS) diagnosed?

A proper diagnosis helps people with FCS get the care they need.

FCS requires special treatment approaches to keep triglyceride levels low, so a diagnosis confirmed with genetic testing may make a big difference in the care they receive – and the life they live.1,36

A doctor can make an initial diagnosis of FCS based on standard clinical testing and examination, but a genetic test can help confirm a diagnosis.1

Distinctive signs of FCS include8:

  • Extremely high TGs of greater than 880 mg/dL or 10 mmol/l on more than one occasion
  • Blood that appears fatty or milky after it is drawn
  • Severe, sometimes daily, stomach pain that often manifests as back pain

Some healthcare professionals may not know about FCS, leaving many people without the help they need managing it.8,36

  • Pancreatitis on more than one occasion or repeated episodes of unexplained, severe abdominal pain
