Elevated Vitamin B 12 results x 2. What are the implications

I have had laboratory work completed with a new Concierge physician for an initial visit then followed by another blood draw a month later for follow-up. The first Vitamin B12 result on 8/28/2025 was 1707 with normal benchmark between 232-1245 per the lab, repeat on 11/18/2025 the B12 value was 1836. All other labs were within normal limits. Has anyone experienced this and what was the outcome or physician recommendations. My physician had none.
