Why you might see this term
It may be needed for tests that cannot use a finger-prick sample, for a larger sample volume, or after an unsuccessful home collection.
What to keep in mind
The required tube, preparation and timing depend on the tests requested. A blood draw is a collection method, not a particular fertility test.
