Related lab tests

For people using Perjeta 420mg Injection as part of their breast cancer treatment, there are certain lab tests that can help monitor their health and response to the medication.

These tests are important to track the levels of certain proteins in the body that can indicate the presence and progression of breast cancer.

CA 15.3 is a tumor marker that can be elevated in the blood of some people with breast cancer. Monitoring the levels of CA 15.3 through blood tests can assist in assessing treatment response and disease progression.

ER and PR tests, on the other hand, help determine if the breast cancer is hormone receptor-positive. This information is crucial for guiding treatment decisions, as hormone receptor-positive breast cancers may respond well to hormone therapy.
