Postive results but Western Blot Negative
 

Hi All,

My wife had some blood work and we found out that;
Anti-Hu Antibody came back positive but; Western Blot after was negative
Also one or 2 others same positive but Western Blot negative

Now I know if western Blot is negative, then it was kind of like a false positive but I am thinking;
Is there anything to be worried about?
Any more testing she should get done?
Any one with similar issues?

Basically I don't understand how 3 cancer/tumor blood test can come back positive but all the Western Blots on them come back negative which si good. Just worried what may have been causing the false postives in the first place for them all?

Thank you so much everybody who will respond
