Depends on the provider and risk factors.
Bloodwork is usually done early on for things like rh factor, baseline blood chemistry/blood cell counts, HIV test, rubella immunity, and things like that. AFP is at around 16 weeks. The newer genetic tests like MaterniT21 are after 10 weeks, but I don't get the impression that this is routinely offered (or covered by insurance) yet. Glucose tolerance test is 24-28 weeks, but may be done earlier and repeated if you have risk factors or a paranoid provider (if you know you have a lot of risk factors, I'd suggest requesting an HbA1C test with the initial bloodwork to get a baseline and make sure you're not already diabetic, as some "gestational diabetes" is actually undiagnosed pre-existing diabetes).
Urine is generally every appointment.
Ultrasounds - many people have one done early (before 8 weeks) for confirmation of a viable pregnancy and date confirmation, but this isn't routinely offered. 11-13 weeks is common for nuchal translucency test and dating. Around 20 weeks is the anatomy scan. They typically want to do a doppler to listen to the heartbeat every appointment after 10 weeks or so.
GBS screening is generally 36-37 weeks, but is sometimes caught in a urine test earlier, and I've heard of practitioners who do the swab routinely early on.
There's probably more I'm forgetting.
