Both of those are really low (if you meant the 4 month was 1.3 and not .13, which is negative). I'd ask for a type specific IgG and see what those say, as it looks like you had a combination test done, which tests for both antibodies together and doesn't differentiate.
Most experts feel that anything under 3.5 is likely a false positive and needs to be confirmed. Since yours is so close to the cut off, I'd definitely agree with that.
