Do these prenatal tests sound normal?

Had an appt with my midwife today and she told me that at my next appt I'll be having lab work done which will include a typical CBC (complete blood count screening), HIV test, chicken pox immunity test, rubella immunity test.

I can't help but think the additional tests sound unnecessary...

I've had chicken pox before so I don't need that test, my husband and i have been together and monogamous for 6 years and I'm 99% sure i dont have HIV, and i had an mmr vaccine 8 years ago...

Do i sound stupid if i deny the extra tests? Also kinda worried my insurance won't cover them
