Osteoporosis and T score

[pussycatwillow]

Does anyone know how the T score is calculated.

My scan

Lumbar Spine -1.9

Femoral Neck -2.2

Then there is

Mean L + R Femur

T Score -2.7

How did they get this figure?

Thanks

as no one has answered your question I hope this will help you although I’m not sure it is what you are actually looking for hss.edu/conditions_dxa-dexa....

You might also have a z score - here’s a bit about them

Thanks for the links,

My individual scores for spine and hip are each below the threshold of -2.5 which is the magic figure for osteoporosis I just wondered how the figure of -2.7 was calculated.

T-scores are calculated from your bone density measurements, comparing those to average for a 30 year old. They estimate bone loss since peak bone density at around age 30. You should have BMD (bone mineral density) figures, which are the basis for t-score calculations. Mean L & R femur is the average t-score for your 2 hips, based on the average for total left hip and total right hip.

Hi Pussycatwillow,

You could ring and speak to a nurse on the helpline they can explain this to you. There is also a fact sheet that explains about DXA scans. strwebprdmedia.blob.core.wi...

Is this from bone scans?
