What Is The Difference Between A 1-Day Protocol And A 2-Day Protocol.
For the 1-day protocol, both the rest and stress portions of the test are performed on the same day, and the test takes approximately 3-4 hours. The 1-day protocol also involves receiving a higher radiation dose. For the 2-day protocol, the rest and stress portions of the test are split into 2 separate days. The rest component takes approximately 1.5-2 hours, and the stress component takes approximately 2 hours. The 2 day protocol is recommended as it involves a lower radiation dose.
