Insulin-Like Growth Factor 1 (IGF-1) Test

Colorado rates for HCPCS 84305

This blood test measures IGF-1, a substance the liver produces in response to growth hormone. Because IGF-1 levels stay more stable throughout the day than growth hormone itself, this test is a useful way to evaluate whether the body is producing too much or too little growth hormone.
