Calories to replace a pint of blood, plasma, or platlets?

[sheepdog.tx]

Curious if anyone hear knows this. I like to give blood regularly but not sure how many calories to add back into my meals for that day to even it out without being under or over. I reading anywhere from 400 to 650 calories, which seems like alot of variance.

But what about just donating plasma? or just platlets?

Thoughts?
