Osteoporosis Patient Education
Common Tests or Labs to Diagnose Osteoporosis
In addition to dietary modifications, patients with gout may need medication to help with flare-ups and pain.
It is important for patients with gout NOT to take aspirin or aspirin-based products, which are high in uric acid.
Please read the following osteoporosis patient education guide to common tests and labs.
|Test||Why Test?||What Happens?||Normal Result|
|Dual X-Ray Absorptiometry (DEXA)||Scans and measures the density of the spine, hip and total body*Test of Choice||If clothing has no snaps, buttons or zippers, no change of clothing is needed.You will lie on a padded exam table while an instrument arm shifts above you, scanning the density of your hip and spine.
You are not enclosed in the machine and leaning on a square cushion raises your legs.
|Normal T score is-1.0 or above.
-1 to -2.5 shows osteopenia:
the start of bone loss.
|Urinary N-Telopeptide Type I collagen (uNTX)||Tests for bone resorption (bone loss). Marker found in the urine||A urine sample is given from a second-morning void of at least 1 ml or a 24-hour urine collection. (volume must be recorded)The specimen must be refrigerated during storage for the laboratory.||Normal is<20 nmol/mM creatinine|
|Bone-Specific Alkaline Phosphatase (bone ALP or BALP)||Evaluates new bone formation rate||A tourniquet (elastic band) is placed around the upper arm and the site for puncture is wiped with an alcohol swab.A needle with syringe is inserted into a vein (usually opposite side of elbow or back of hand) and blood is withdrawn for analysis.||Normal is 20 to 140 IU/L|
|Level of Vitamin D||Pinpoints any deficiency, which prevents calcium absorption despite amount of calcium consumed.||A tourniquet (elastic band) is placed around the upper arm and the site for puncture is wiped with an alcohol swab.A needle with syringe is inserted into a vein (usually opposite side of elbow or back of hand) and blood is withdrawn for analysis.||50-80 ng/ml|
