How long can you store blood for a blood alcohol test?

Blood samples for alcohol testing can typically be stored for a limited time, usually up to 24 hours at room temperature. If refrigeration is used, samples can be stored for up to several days, but it's best to analyze them as soon as possible for accurate results. For long-term storage, samples should be frozen, which can preserve them for months, though this may not be standard practice for routine tests. Always follow specific guidelines and protocols for handling and storing blood samples.
