Tests
A BRAF genetic test uses a sample of tumor tissue, bone marrow, or blood to look for changes in a gene called BRAF . Changes in your genes are also called gene variants or mutations. The test is usually done to look for changes in the BRAF gene that may be involved in cancer .
Tests
A calcitonin test uses a sample of your blood to measure your levels of calcitonin, a hormone made in your thyroid gland by cells called “C cells.” Your thyroid is a small, butterfly-shaped gland in your neck, and C cells grow on the inside part of your thyroid (the medulla).
Tests
The determination of the amount of EGFR variant protein present in a sample.
