Tay–Sachs disease possible carrier?

I was told by my OB that my blood work came back abnormal. Half of my Tay-Sachs testing came back fine and the other half came back showing a slightly rare possiblility that I'm a carrier of some branch of Tay-Sachs. I wish I could remember the name she gave me... She told me not to google it, but my mind has been running laps over what she said. Has anyone ever experienced this before?
