COVID-19 Antibody Test (SARS-CoV-2 AB IgG), Semi-Quantitative Results

I was wondering if anyone has had this test done or can provide some resources to help understand what the results mean.

My results simply say > 150.00 index. I understand this is a semi-quantiative test but i am having trouble finding population results post vaccine to interpret these findings. If anyone can shed some light on this, it would be greatly appreciated!
