How long will 1 Tylenol 3 show up in a blood test?

Tylenol 3, which contains acetaminophen and codeine, can typically be detected in the blood for up to 24 hours after ingestion. However, factors such as individual metabolism, dosage, and frequency of use can affect detection times. While acetaminophen may clear from the system more quickly, codeine can be detectable for a longer period, usually up to a few days in some cases. Always consult a healthcare professional for specific concerns regarding drug testing.
