If it doesn’t look good at that point, immediately start a different therapy.
You may already get this blood test as part of your annual physical. There’s no need to wait a lot of precious months, now.
Thanks for your medical post I appreciate it
It seems pretty clear from your comment you don't know what you're talking about.
CAR-T is not a front-line therapy. By the time you might possibly get to this therapy as a patient, you've had multiple failed attempts at other treatments. So, there is so much more than a simple blood test to make that determination. So much more!
In fact, it's a therapy that is incredibly complex and expensive (approximately $500,000) and is performed by only a few centers around the country. By the time a patient gets to CAR-T treatment, they've had multiple failed treatments and have been exposed to the best screening and analysis that modern medicine can offer.
A "simple/cheap blood test with an annual physical" for a rare disease and as a screening mechanism for the use of an incredibly complex treatment is just plain foolish beyond understanding.
Don't mislead us.
