Is there anything that can mess up a blood pregnancy test such as a refrigeration?

Hello. No, nothing can mess up a blood pregnancy test unless you wasn't given someone elses result which is highly unlikely. Regarding the refrigeration of the blood test, well this wouldn't affect the pregnancy test because the refrigeration will be set at the precise level for this test to be completed. So dont worry about this. But if you're worried, then see your doctor for a QUANTIATIVE BETA HCG blood test. This test is highly accurate.
