Crazy high numbers

I've always had high total cholesterol (around 300), but I've never seen it this high. I booked an appointment with a cardiologist soon and I'm trying to get on PCSK9 inhibitors directly. I'm a male, early 40s.

Has anyone seen a transient spike like this? One possible explanation is a recent Covid infection (4 weeks prior) that knocked me out for about 10 days.
