A bit atypical: A bit more information would be helpful. How high are your C4 levels and does "low C1" mean C1q or CI-INH. Were these levels checked during an "attack" or in between "attacks". High C4 levels are not classic of the various hereditary angioedema variants.

Repeat tests: The C4 is usually low in HAE but can be normal with the inherited kind.You may repeat the test to make sure
