Medical person: what is my doctor looking for?

The lab order form says:
Basic Lipid (AMA) (S)
Comprehensive Metabolic (AMA) (S)
ANA w/reflex Titer (S)
CBC with diff & platelets (L)
Sedimentation rate (ESR) (L)
TSH (H) – marked with the note: reflex free T4
Vit. B12/Folate (S)

I can look up what these things are individually, but I don’t get a bigger picture from them. What does he think I might have?
