ANA testing time

Hello, I've been having chronic symptoms for years with increasing in amount and severity--fatigue, hair loss, photosensitivity, joint pain, body aches like with a fever, excessive sweating, pleurisy, bradycardia, muscle soreness. I was referred to a rheumatologist and saw him on Friday. He ordered a lot of tests and the ANA titers was one of them. I had my blood drawn Monday morning and the results are already in my health track this morning. I was under the impression that this test took a least 3-4 days. Is this test back too quickly? I know most of the time we want answers fast, but we also want a correct reading. How can you know if there was a mistake made with your testing? Should I have this redone?

I agree w/ Lynnwood. I was told a week and got a call 2 days later.
