Why you might see this term
Some laboratory tests can use a properly collected capillary sample. The kit specifies how much blood is needed, collection timing and return requirements.
What to keep in mind
A finger-prick kit is not suitable for every marker or situation. Follow the provider’s validated instructions; a venous sample may be needed if collection is unsuccessful.
