Laboratory Studies

In hereditary angioedema (HAE), routine laboratory test results are usually normal, although a leukocytosis may occur with gastrointestinal episodes. Elevation of the hematocrit value may be observed because of intravascular fluid loss. The most reliable and cost-effective screening test is a C4 level.[8] If the C4 level is in the normal range but suspicion for angioedema is high, the test should be repeated.[6]

For type I HAE, see the following:

  • C1-INH level is low.
  • C4 and C2 levels are low.
  • C1q level is normal.

For type II HAE, see the following:

  • C1-INH level is normal or elevated but dysfunctional.
  • C4 and C2 levels are low.
  • C1q level is normal.

For type III HAE, see the following:

  • C1-INH level is normal.
  • C1-INH functional assay is normal.
  • C4 level may be normal.
  • Factor XII mutation may be present.[5, 11]

Imaging Studies

In hereditary angioedema (HAE), abdominal radiographs may demonstrate features of ileus. Abdominal ultrasonography or computed tomography may show edematous thickening of the intestinal wall, a fluid layer around the bowel, and large amounts of free peritoneal fluid. Chest radiographs may demonstrate pleural effusions.

Histologic Findings

Histologic features of hereditary angioedema (HAE) include edema in the reticular dermis or subcutaneous or submucosal edema without infiltrating inflammatory cells. Vasodilation may be present.
