Low calcium.. Could this be Correct?

[Mikef1]

I just tested my calcium in my tank for the first time since it cycled. I used an older test kit so this could be the culprit. Just wanted to know if these measures could be correct.
PH 8.3
ALK 12.2
Calcium 220
This calcium reading seems extremely low for a newly established tank after doing 2 large water changes and considering PH and alk seem to be good. Alk could be a bit high though. Any input would be appreciated.

Take a sample in and check it against your kit. Your alk may only be slightly high, but alot of people keep their alk up there.
