Yes, you’ll likely need to have lab tests done before you receive each dose of Yervoy. This is to make sure it’s safe for you to use the drug. Your doctor may also order lab tests if you have symptoms of certain side effects during treatment with Yervoy.
Examples of lab tests your doctor may order include:
liver enzymes
creatinine
adrenocorticotropic hormone (ACTH)
thyroid hormones
blood sugar
blood counts
electrolytes such as potassium, sodium, and calcium
If any of these lab tests show a problem, your doctor will decide if it needs to be treated. They can also determine if your next dose of Yervoy should be delayed or if you should stop treatment completely.
