Is serum phosphorus the same as serum phosphate?
Yes, serum phosphorus and serum phosphate are often used interchangeably to refer to the level of inorganic phosphate in the blood. Phosphate is the ionized form of phosphorus.
How bioavailable and useful is TriCalcium Phosphate as a form of dietary Calcium in humans?
The design was randomized crossover, within-subject. The subjects were 25 healthy premenopausal women in an academic health sciences center. Two commercially marketed calcium-fortified orange juices, ingested in an amount providing 500 mg calcium, were taken at breakfast after an overnight fast. The two fortification systems tested were calcium citrate malate and a combination of tricalcium phosphate and calcium lactate (tricalcium phosphate/calcium lactate). The main outcome measure was the area under the curve (AUC) for the increase in serum calcium from 0 to 9 hours after ingesting the test calcium source. Statistical analyses performed were repeated measures analysis of variance, testing source, and sequence. AUC 9 was 48% greater for calcium citrate malate than for tricalcium phosphate/calcium lactate ( P < .001); absorbed calcium calculated from AUC 9 values (mean+/-standard error of the mean) was 148+/-9.0 mg and 100+/-8.9 mg for calcium citrate malate and tricalcium phosphate/calcium lactate, respectively. The results indicate that equivalent calcium contents on a nutritional label do not guarantee equivalent nutritional value. Nutritionists and dietetics professionals should encourage manufacturers of fortified products to provide information on bioavailability.
What is the calcium correction for albumin?
To correct calcium for albumin levels, you can use the following formula: Corrected calcium (mg/dL) = measured total calcium (mg/dL) + 0.8 * (4 - serum albumin in g/dL). This correction is important because albumin levels can affect the total calcium levels in the blood.
What is the clinical reference range for serum sodium and serum potassium?
The clinical reference range for serum sodium is typically between 135-145 mmol/L, while for serum potassium it is usually between 3.5-5.0 mmol/L. These values may vary slightly depending on the laboratory performing the analysis.
What is serum chloride?
Serum chloride is a measurement of the amount of chloride ions in the liquid component of blood (serum). It is an important electrolyte that helps maintain proper balance of bodily fluids and plays a role in maintaining blood pressure, pH balance, and overall hydration levels in the body. Abnormal levels of serum chloride can indicate certain medical conditions or imbalances in the body.
How is Phosphorus imbalance observed?
Disorders of phosphate metabolism are assessed by measuring serum or plasma levels of phosphate and calcium
Is serum phosphorus the same as serum phosphate?
Yes, serum phosphorus and serum phosphate are often used interchangeably to refer to the level of inorganic phosphate in the blood. Phosphate is the ionized form of phosphorus.
What is the relation of 'steroid suppression test' with parathyroid gland?
My impression is that the steroid suppression test (Dexamethasone test) is to help differentiate between primary hyperparathyroidism from hypercalcaemia secondary to increased corticosteroids levels. Idea 1: corticosteroids reduce calcium and phosphate absorption and inhibits bone formation (this is the catabolic arm of the cortisol stress response). Therefore, if there is a high level of corticosteroids, the result would be decreased serum calcium and phosphate. Idea 2: Lowered serum calcium and phosphate levels would in turn upregulate parathyroid hormone production to increase serum calcium and phosphate levels caused by Idea 1. Idea 3: A patient with hypercalcaemia could be given a steroid suppression test. If the hypercalcaemia were secondary to the steroids, then one would expect a responsive lowering of parathyroid hormones.
What is corrected calcium?
measured serum calcium + (40-serum albumin)/50
What does spo4 stand for?
serum phosphate
What parathyroid hormone increases serum calcium levels?
PTH activates vitamin D in the body, which absorbs calcium and phosphate from foods. It works on the intestine to increase the absorption of calcium. It causes the bones to release more calcium, and causes the kidneys to reabsorb more calcium. This all helps to increase calcium levels.
Why would serum calcium be elevated in osteoporosis?
Serum calcium will be depleted in advances osteoporosis. Calcium mostly resides in the bones. In osteoporsosis, the bone is being broken down faster than the body can rebuild it. This causes calcium stores to go from the bones and into the blood stream. Serum calcium is the measure of calcium in the blood, not what is in the bones.
What level should serum calcium be at?
The normal range for serum calcium levels is typically between 8.6 to 10.3 milligrams per deciliter (mg/dL). However, optimal levels can vary depending on individual health factors, so it's best to consult with a healthcare provider for personalized guidance.
Two endocrine glands responsible for the maintenance of serum calcuim?
The parathyroid glands and the thyroid gland are responsible for the maintenance of serum calcium levels. The parathyroid gland secretes parathyroid hormone (PTH), which increases serum calcium levels by stimulating calcium release from bones and increasing calcium absorption in the intestines. The thyroid gland secretes calcitonin, which helps regulate calcium levels by inhibiting the release of calcium from bones.
Serum calcium levels may be used to test for abnormalities in which body system?
Serum calcium levels may be used to test for abnormalities in the kidneys. Low calcium levels can be an indication of a kidney disease. Likewise, thyroid and parathyroid diseases also are possible when there is an abnormal serum calcium level.
What affect do phosphates have on serum calcium in the blood?
Oral phosphates can lower serum calcium levels, but the long-term use of this approach is not well understood.
How do you measurement calcium and phosphate using a spectrophotometer?
The appearance of kits for the determination of micro amounts of calcium stimulated our interest in the use of Eriochrome Blue SE for this analysis. A study of spectrophotometric curves indicates that, at pH values above 13.7, calcium will complex and cause a change of dye absorbance while magnesium does not complex with the dye. A differential spectrophotometric technic is described in this paper in which the spectrophotometer is set at zero absorbance with a dye-calcium standard solution or a dye-calcium sample solution as reference and the absorbance of the dye solution then measured. For a set of standards the absorbance-calcium relationship is linear. With the Beckman spectrophotometer, Model Dli, it has been found that 1 part of serum to 100 parts of alkaline dye solution (100 A of serum to 10 ml. alkaline dye solution) can be used. The technic shows greater sensitivity and accuracy than do previous methods using Eriochrome Blue SE.
