🌙 Vitamin D 25 Oh D3 Normal Range

Reference ranges for 1,25 (OH) 2 D may be reported as either pg/mL or pmol/L. The molecular weight of 1,25 (OH) 2 D is approximately 416.7, yielding the following conversion factors: 1 The Endocrine Society, the National and International Osteoporosis Foundation, and the American Geriatric Society define vitamin D deficiency as the level of 25-hydroxyvitamin (25 OH D) of less than 30 ng/mL. The Endocrine Society recommends a preferred range of 40 to 60 ng/mL. The consensus is that levels of 25(OH)D below 25nmol/L indicate 'deficiency'. Some have argued that this level is conservative. Raising the definition of "deficiency" or "sufficiency" to higher levels is inappropriate until results from randomised trials can show that maintaining such levels has clear health benefits and no health risks. 25-OH Vitamin D Calcidiol D2 D3 Vitamin D Assay 25HDN 25OHD 25DEP Calciferol Ergocalciferol Cholecalciferol Colecalciferol CYP2R1 Diagnosis of vitamin D deficiency Differential diagnosis of causes of rickets and osteomalacia Monitoring vitamin D replacement therapy Diagnosis of hypervitaminosis D An intake of no less than 1000 IU (25 mcg) of vitamin D3 (cholecalciferol) per day for all adults may bring at least 50% of the population up to 75 nmol/l. Thus, higher doses of vitamin D are needed to bring most individuals into the desired range. Function Deficiency Vitamin D sources Toxicity Contacting a doctor Summary For adults, a level of vitamin D in the blood of 20 nanograms per milliliter (ng/mL) or above is generally Normal Results. The normal range of 25-hydroxy vitamin D is measured as nanograms per milliliter (ng/mL). Many experts recommend a level between 20 and 40 ng/mL. Others recommend a level between 30 and 50 ng/mL. The examples above are common measurements for results of these tests. Vitamin D deficiency (serum 25-hydroxyvitamin D [25 (OH)D] < 50 nmol/L or 20 ng/ml) is associated with unfavorable skeletal outcomes, including fractures and bone loss. A 25 At that time, their experts concluded: "Based on all the evidence, at a minimum, we recommend vitamin D levels of 30 ng/mL, and because of the vagaries of some of the assays, to guarantee sufficiency, we recommend between 40 and 60 ng/mL for both children and adults." Normal Results. The normal range of 25-hydroxy vitamin D is measured as nanograms per milliliter (ng/mL). Many experts recommend a level between 20 and 40 ng/mL. Others recommend a level between 30 and 50 ng/mL. The examples above are common measurements for results of these tests. Normal value ranges may vary slightly among different laboratories. The amount of 25-hydroxyvitamin D in your blood is a good indication of how much vitamin D your body has. The test can determine if your vitamin D levels are too high or too low. The The major circulating form of vitamin D is 25-hydroxyvitamin D (25(OH)D); thus, the total serum 25(OH)D level is currently considered the best indicator of vitamin D supply o5CAS.
