Understanding Lab Tests for Cystic Fibrosis
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Cystic fibrosis (CF) is a genetic disorder that primarily affects the lungs, pancreas, liver, kidneys, and intestines. While CF is diagnosed through genetic testing and sweat chloride tests, blood tests play a crucial role in monitoring disease progression, assessing complications, and evaluating the body's response to this complex condition.
Recommended Test
Lysozyme
This test measures lysozyme levels in the blood, an enzyme that is often elevated in patients with cystic fibrosis. Elevated lysozyme levels can reflect the chronic inflammatory processes and immune system activity that characterize CF, making it a valuable marker for monitoring disease activity and progression.

The Role of Blood Testing in Cystic Fibrosis
Although there isn't a single blood test to diagnose cystic fibrosis itself, blood testing is fundamental for monitoring various biochemical changes that occur in CF patients. These tests help healthcare providers assess organ function, track disease progression, and identify potential complications related to chronic inflammation and infection.
Understanding Lysozyme in Cystic Fibrosis
Lysozyme is an enzyme naturally produced by the body as part of the immune system's defense against bacteria. In cystic fibrosis, the chronic infections and persistent inflammation that affect multiple organ systems can lead to consistently elevated lysozyme levels, making this test useful for ongoing monitoring of CF patients.
