How to Read a CD117 Test

A CD117 test determines if you're positive for cancerous tumors. A CD117 test is also known as a c-kit test. C-kits are cytokine receptors that can be found upon your cells, such as stem cells. According to the National Cancer Institute, if c-kits become altered, abnormal growths within your cells can result in some forms of cancer. If you receive a positive result for your CD117 test, it is important to consult with your physician to help your understanding of the results.

Instructions

Test Interpretation

• 1

  Confer with your physician on the results of your test. A positive test will result when a sample of your cancerous tissue is stained with antibodies (proteins found within fluids such as your blood) and the tissue is proven to be identified with c-kit receptors.

• 2

  Don't be afraid to ask what a false positive or false negative test means. It is possible for a c-kit test to be inaccurate. For example, a false positive test can occur due to another underlying medical condition, which may require further diagnostic testing.

• 3

  Get retested if you receive a borderline result for your c-kit test. A borderline test occurs when the test hasn't provided a significantly positive result. This means that the test did not result in a 100 percent finding.

• 4

  Don't immediately pursue treatments such as chemotherapy or surgery, even if you have a positive c-kit test. According to the site Leiomyosarcoma, you can confer with a "sarcoma oncologist specialist" to learn about treatment options like Glivec (a cancer medication).
