Acth stimulation test results: baseline cortisol 6.2, 30 min 19.4, 1 hour 22.7. suspect sai?

While there can be: variation between labs, these results appear to be largely normal. The baseline is normal (5-23 micrograms per deciliter). A rise from baseline of at least 7 to 10 ug/dl of cortisol, reaching at least 18 ug/dl at 60 minutes post-stimulation rules out primary adrenal insufficiency. A blunted response (not sure yours qualifies) may suggest secondary AI. Your Doctor will advise you. Stay well.
