Called baxk for 2nd blood test aftee seizure

[Daffodil1993xxxx]

Hospital today as seizure happened at work (do have epilepsy)

No major injuries , blood tests done and sent home after being checked over

Hospital called back and asked to come back tomorrow for more blood tests ?

Why may this be ? Should I be worried?

Some sort of mention of dehydration??

Likely just a recheck as something is out of range. often potassium, which is part of a kidney function test, is raised if people are dehydrated or can be raised if the tourniquet has been on too long as they’ve struggled to get a sample.
Its often back in normal range on retesting.
