my gastrin came in at 39, which is lowish but not clinical. i want that more around 50-75 when fasting; it came in at 76 after a meal.

so, i'm not producing as much gastrin as i'd like and that might be some key information, although where i go with it is less clear. 

the osteocalcin came in at 18, which is on the higher end of turnover markers. but, i was fasting, so my body may have been using my bones for minerals. this seems to be a delicate metric - 18 is considered to be normal, 19 is considered to be osteopenia and 22 is considered to be osteoporosis.

i would have liked this number to be a little lower, and the most likely cause is indeed estrogen deficiency combined with not eating. ii wish i had done it without a fast... 

so, should i do it again? not yet - there's other markers to look at that don't cost $70.
