Blood Drug Testing

Do blood tests to check for cancer also test for toxins in the system?

I have symptoms of lymphoma and I'm going to the doctor tomorrow to get a blood test. Will this test also show toxins (THC, etc.) that are in my body?

1. With something like this, especially if the doctor knows why you are running these blood tests, they will test for everything that could showing these symptoms, including your THC levels.
2. There are no blood tests to test for cancer. If you have lymphoma your labs would be off and that would indicate it could be cancer and followed by a biopsy. They do not check for “toxins”. If you are concerned about being positive for drugs, the doctor would have to ask the lab to specifically test for those drugs he or she wants tested.
3. There aren't cancer blood tests. Lymphoma is a blood disease, but it tests for white cells, etc. Don't worry about the pot you smoked.
