[There's a thoughtful hum from Alucard.]

If you feel any changes, you should let me know at once. For now, allow me to check your other vitals.

[He gently takes her wrist, only to feel for her pulse. Once he's satisfied, he pauses.

Alucard doesn't have a device to check her weight, but... well. He can do this.

With ease, he picks her up under the armpits, frowning as he tries to evaluate her weight.]

I've little else to add. You seem, all around, to be a normal human girl. Slightly underweight, but not to an unhealthy degree. Pulse is reasonable.
