Can CCP Report Values Drop Suddenly In 5 Days?

My first anti ccp report depicted around 69 U/mL, and i was put on trypsin and chemotrypsin medication for 5 days. After five days when I got the same test done from another path lab the resukts showed an anti ccp level of 1.25 U/mL. Is such a drop in 5 days possible?

Hello and welcome to HCM,
The second anti-CCP test should be carried out in the same laboratory using the same method as the first.
Different laboratories can use different methods to perform the same test.
A comparison can only be made when the investigation is performed in the same laboratory by same method.

Thanks and take care
