Parathyroid hormone at 170pg/ml, vit d at 8ng/ml, calcium serum 10.2 yesterday and 9.1 today, bone mineral density t-score -1.5.. what does this mean?

Listen to your body: Vit d3 is deficient, parathyroid is excessive and bone density is decreased and calcium is on the high side of normal. Phosphate intake and blood levels may be increased causing parathyroid levels to be high. Magnesium may also be deficient. Re-evaluate life style. Eat 6 healthy meals with 6 servings of fresh green vegetables, get sufficient vit d3 from sun or supplements, avoid colas.

Bones, Vit D: This is complex, and a precise answer cannot be given on line. Several thoughts: the PTH is high. But this may not reflect anything wrong with the parathyroid glands. Low vit d will result in a reflex increase in pth, and usually the serum ca stays normal, but there is increased bone resorption. Why is the vit d so low?
