What usually happens next

The most common reason is low albumin, the protein that carries calcium: a corrected calcium or an ionised calcium shows the real level.

If it's truly low, vitamin D, magnesium, PTH and kidney function are the next tests.

When a calcium can read wrong

Most calcium in blood rides on albumin, so a low albumin makes total calcium read low and dehydration makes it read high. A long tourniquet can nudge it up. A corrected or ionised calcium settles it.
