Why causes CBC results to cycle thru out day?

[waterbottle10]

I saw someone w q12 lab work, and the morning one is always lower than the night one, for past week. Is there something that can cause this? there are no transfusions. None of the other ppl I saw showed this so. for example, in the morning wbc would be like 2, at night it'd be 3. next morning its 2, then night is 3. same with CBC, itd go 8 9 8 9 morning night. Platelets would go like 100 130 100 130..

Anyone kno what could be causing this?

I think he meant Hemoglobin. Every time you draw someone's blood you technically are changing their numbers.
