Finished chemo but still have to do Herceptin

Wondering if anyone who is continuing with Herceptin after chemo can answer my query. Do you still have to have regular blood tests before each injection the same as when having chemo? Marli x

You still have to have blood tests but not as often I think it is about every 10 weeks or so

I have to have blood work every three months while on Herceptin.
