Why Did my numbers go up ?

So I redid my test to confirm... But o well its true I do have HS2 😔😔😔😔 My question is why did my IGG go up from 5.32 to 6.11 go up again my IGG can somebody please explain....

Test from

5/8/2017

HSV 1 IgG Type Spec Ab <0.90 <0.90

HSV 2 IgG Type Spec Ab 6.11 H <0.90

4/20/2017

Hsv 1 IgG Type Spec Ab<0.90<0.90 

HSV 2 IgG Type Spec Ab 5.32  H<0.90 

Could be a fluctuation that doesn't mean anything (you won't always get back the same number on these tests; some fluctuation is normal), or it could be indicative of a new infection. If the numbers go up much more after another month, for example, then it's a new infection.

Ok thank you....
