What is a normal z score in bone density

Eventually, enough data was collected so bone density Z-scores could be measured against large sub-populations.Z-score The Z-score is the comparison to the age-matched normal and is usually used in cases of severe osteoporosis.T-score: Your T-score is the difference between your bone density and the average bone density of young, healthy woman.The BMDCS Protocol The primary goal of BMDCS was to obtain standard pediatric reference data for bone mineral density.The World Health Organisation (WHO) defines osteoporosis as a T-score less than -2.5 SD. However, Z-scores are mor.Nevertheless, bone densitometry T-scores at the spine remain a very useful measure in the determination of osteoporotic status.If you score between-1 and-2.5 you have osteopenia, which means you are beginning to lose bone mass but do not yet have osteoporosis.The T score is based on young adult women who have normal bone density.

Lower scores (more negative) mean lower bone density: A T-score of -2.5 or lower qualifies as osteoporosis.What the Numbers Mean: A positive T-score, or a negative score up to -1.0 means your bones are in good shape.

The score indicates if your bone density is normal, below normal, or at the levels that indicate osteoporosis.Later bone density was measured in large populations and the Z-scores were compared to the general population and not just to healthy people.

The present study was designed to test the hypothesis, by determining reference range of peak bone density for an Asian population, and then comparing the concordance between a population-specific T-score and the DXA-based T-score in the diagnosis of osteoporosis.Although no bone density test is 100-percent accurate, the BMD test is an important predictor of whether a person will have a fracture in the future.

They divided them into four groups: those with normal T scores (a measure of bone density), those with mild osteopenia (less severe bone loss that often progresses to osteoporosis), and those with moderate or severe osteopenia.This score gives a reading of your bone density in comparison with other individuals of your weight, sex, racial or ethnic background, and age.BMD datasets are machine-specific, therefore the correct DXA manufacturer must be selected.

It will also include a Z-score that compares your bone density with others who are the same age, race and sex.

The T-score report will show your bone density measurements compared with the normal bone density of a healthy adult of the same gender.Put simply: a T-score of above -1 is normal, between -1 and -2.5 the bone mineral density is lower than would be expected (this can also be called osteopenia) and a score of below -2.5 indicates that you have osteoporosis.A Z score of 0 is the mean bone density of people of the same age, sex, and genetic background.The more minerals there are, the higher your bone density will be.I just met with my gyn today to go over my bone density measurement test results.
