Is this IgG negative really a negative?

[Dollhairs]

I just had my first ever cold sore. I fought it like hell with Abreva, so it hung around and flared up and down for more than a month before it finally ran full cycle. I haven't had unprotected sex since my last test, but have definitely kissed people. Got a full panel std because i dont like surprises. My cold sore was in scab phase when samples were collected. Below are my HSV IgG results. I realize it says theyre both negative per range, but how could that be with a cold sore? And it was definitely a cold sore.
HSV type I: 0.11
HSV type II:0.07
Negative range for both is below 0.90

Do i need a retest? How worried should i be about that HSV 2, which i wasnt expecting at all? Does this mean i should discuss these results with any potential new partners? Should i seek medicine to prevent future cold sores?

If that was a primary hsv outbreak then you would most likely test negative. The test looks for antibodies the body produces to combat the virus. Not the virus itself. The antibodies take time to develop.
Also, the hsv1 blood test can miss up to 30% of infections. Your correct course of action should've been to see your Dr and get the sore swabbed and tested.

Oh and to follow up: i got the test done by a private lab so havent had Dr. Consult yet. I scheduled an appointment with my Dr., but earliest available is in several weeks and i need to know how worried to be between now and then
