What is the normal reading for calcium in the body?
The serum level of calcium is closely regulated with a normal total calcium of 2.2-2.6 mmol/L (9-10.5 mg/dL) and a normal ionized calcium of 1.1-1.4 mmol/L (4.5-5.6 mg/dL). The amount of total calcium varies with the level of serum albumin, a protein to which calcium is bound. The biologic effect of calcium is determined by the amount of ionized calcium, rather than the total calcium. Ionized calcium does not vary with the albumin level, and therefore it is useful to measure the ionized calcium level when the serum albumin is not within normal ranges, or when a calcium disorder is suspected despite a normal total calcium level.Corrected calcium levelOne can derive a corrected calcium level when the albumin is abnormal. This is to make up for the change in total calcium due to the change in albumin-bound calcium, and gives an estimate of what the calcium level would be if the albumin were within normal ranges.Corrected calcium (mg/dL) = measured total Ca (mg/dL) + 0.8 (4.0 - serum albumin [g/dL]), where 4.0 represents the average albumin level in g/dL. in other words, each 1 g/dL decrease of albumin will decrease 0.8 mg/dL in measured serum Ca and thus 0.8 must be added to the measured Calcium to get a corrected Calcium value.Or: Corrected calcium (mmol/L) = measured total Ca (mmol/L) + 0.02 (40 - serum albumin [g/L]), where 40 represents the average albumin level in g/Lin other words, each 1 g/L decrease of albumin, will decrease 0.02 mmol/L in measured serum Ca and thus 0.02 must be added to the measured value to take this into account and get a corrected calcium.When there is hypoalbuminemia (a lower than normal albumin), the corrected calcium level is higher than the total calcium.
What are Prerequisites for collection of blood sample for serum calcium level estimation?
To collect a blood sample for serum calcium level estimation, no specific prerequisites are typically required. However, it is recommended to fast for a few hours prior to the test, avoid strenuous exercise before the test, and inform the healthcare provider about any medications or supplements being taken that may affect calcium levels.
What are the effects of lipemic sample on serum electrolyte?
A lipemic sample can interfere with the measurement of serum electrolytes by causing a falsely elevated potassium level due to the turbidity of the sample. Lipemia can also interfere with the accurate measurement of sodium, chloride, and bicarbonate levels in the serum. It is important to properly clear the sample of lipids before analyzing electrolytes to ensure accurate results.
What tube use for Digoxin level?
A red top tube (serum separator tube) is typically used to collect blood for digoxin level testing. The tube should be inverted gently to mix the blood with the anticoagulant and clot activator present in the tube. Once the sample is collected, it should be processed promptly to separate the serum for analysis.
What is the pH level of calcium hydroxide?
The pH level of calcium hydroxide is around 12-13, making it alkaline.
Does hypercalcemia cause muscle tetany?
Hypocalcemia ( a low serum calcium level), not hypercalcemia ( a high serum calcium level), tends to cause muscle spasm and in severe cases may lead to muscle tetany.
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 Hormone responds to high levels of calcium in the blood?
Calcitonin is the hormone that responds to high levels of calcium in the blood by promoting calcium deposition in the bones, thus helping to lower blood calcium levels.
Could a low vitamin d level elevate serum blood calcium?
yes
What is corrected calcium?
measured serum calcium + (40-serum albumin)/50
What kind of endocrine gland is characterized by a low level of calcium in the blood serum and urine?
Do you mean an endocrine gland that can lower calcium level? If this is your question, the answer is thyroid gland. It produdes calcitonin that lowers calcium level opposing the effect of parathyroid gland which increases calcium level.If you mean, a condition that is characterized by low level of calcium in blood, it is called hypocalcemia.
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.
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.
What level should serum sodium be at?
The normal levels of serum potassium are 3.5-5.0 mM

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.
