My L1 was my weakest link and remains so. Before treatment, my L1 TBS was 1.115. It increased to 1.225 after completing Forteo, although the value did fluctuate and at one point was as high as 1.276. My L2 TBS also moved up and down even though it remained in normal range most of time. This suggests the inherent variability in TBS measurements.

Would love to hear your physician's perspective as you move forward.
