Results of bone density tests can be reported in several ways:

* Your bone mineral density (BMD) is usually measured in units of grams

per square centimeter (g/cm2).

* Your BMD value will be compared to other people of your age and sex.

This is your " age-matched " value. It is given in standard deviations

(SD) from the average value for your age group (Z-score). A negative

(-) value indicates that you have thinner bones (lower bone density)

than the average of people in your age group. The more negative the

number is, the less bone density you have compared with others in your

age group. A positive (+) value indicates that you have higher bone

density than the average of people in your age group.

* Your BMD value will also be compared with the average value for a

young (30-year-old) healthy person of your sex. This is the " young

normal " value or T-score. A negative (-) value indicates that you have

thinner bones (lower bone density) than an average 30-year-old. The more

negative the number is, the less bone density you have compared with an

average 30-year-old. A positive (+) value indicates that you have higher

bone density than an average 30-year-old.

Bone Mineral T-score Results mean:

Density (BMD)

Normal: at least 0 SD no bone thinning

Borderline low: -0.5 to -1.0 SD mild bone thinning

Low: -1.0 to -2.5 SD significant bone thinning (osteopenia)

Very low: less than -2.5 SD osteoporosis

BMD test results that are lower than normal can be interpreted in

several ways.

* Doctors usually use the lowest T-score to diagnose osteoporosis. For

example, if a T-score of -3 was obtained at the spine and a T-score of

-2 was obtained at the hip, the spine

measurement would result in a diagnosis of osteoporosis.

* The more negative your T-score, the greater your risk of breaking a

bone during a fall or from a minor injury.

* Every change of 1 SD means a two-fold change in the risk of fracture

at that site. For example, a T-score of -1 indicates a risk of fracture

that is 2 times greater than a T-score of 0.

* Low BMD values may be caused by other disorders, such as

hyperthyroidism, hyperparathyroidism, multiple myeloma, Cushing's

syndrome, ankylosing spondylitis, rickets, premature menopause, or a

vitamin D deficiency.

Your bone density does appear to be on a decline. It is problamatic

whether increasing supplementation from 2000 to 2500 mg of calcium a day

would help. Changing from three doses to four might help a little. One

problem might be that you are taking 2000 mg of calcium citrate thinking

that you are taking 2000 mg of calcium. Calcium citrate is only 21-29%

calcium. If you are taking 2000 mg of just calcium citrate, your net

calcium is 420-580 mg. One way to tell is by the number of calcium

capsules you are taking. If you are taking capsules, you have to be

taking 10 size #00 capsules, the largest usable for human consumption to

net 2000 mg elemental calcium from calcium citrate. If you are taking 4

small capsules of calcium citrate, and think you are getting 2000 mg of

calcium, you are being duped by product mislabeling.

I can't find last years but wanted to run the differences past ya's.

Thanks Ray, it actually makes some sort of sense to me now.

I know my PTH values have been high in the past. Need to get that tested again.
