Serum Phosphorus

Serum Phosphorus

Serum Phosphorus is a test that measure the amount of Phosphorus in your blood. The total amount of phosphorus in our body is 530 grams and 87% of it is found in bones, while the other Phosphorus found in the blood and tissues. Also, phosphorus is found in many foods.

• Lipids
• Proteins
• Co-Enzymes
• Nucleic Acid

Apart from this, Phosphorus is very important in acid-base regulation, especially in the kidneys. Phosphorus in the blood is found in the following conditions:

1. Inorganic Phosphorus
2. Organic phosphorus
3. Phosphorus within Lipid
4. Residual Phosphorus

Red blood cells contain more phosphorus than plasma. Phosphorus is absorbed along with calcium in the jejunum and absorbed into the skeleton. And phosphate is excreted from the kidneys. And there are two ways by which phosphate is excreted from the body through the kidneys.

• Glomerular filtration
• Active tubular reabsorption

Hyperphosphatasemia:

If the amount of phosphorus in the body exceeds the normal amount, it is called Hyperphosphatasemia.

Conditions:

In chronic nephritis, phosphorus becomes high in the body. Renal Failure Phosphorus level reaches 20 mg/dl. This is the post stage of renal failure and urinemic status also occurs at this stage. If bones are fractured, the amount of phosphorus increases even while healing.

Hypophosphatemia:

Phosphorus deficiency occurs in the body in the following conditions.

• Phosphorus is depleted in Ricketts.
• Osteomalcia
• Secondary Hyperparathyroidism
• Chloroform anesthesia should be given
• If someone is given insulin

Is This Test Have Other Name:

Serum Phosphorus, Phosphorus Level, Po4,

How The Test Performed:

A Blood Sample Needed.

Why do I need a Serum phosphorus test?

Your doctor may order a serum phosphorus test if they suspect that your phosphorus level is too low or too high. Either extreme can lead to health problems.

Symptoms that may indicate your phosphorus level is too low include:

changes in your mental state (for example, anxiety, irritability, or confusion)
bone issues, such as pain, fragility, and poor development in children
irregular breathing
fatigue
loss of appetite
muscle weakness
weight gain or loss

Principle:

Inorganic phosphorus, with ammonium molybdate reacts in the presence of sulfuric acid and forms a phosphomolybdate complex which is measured at 340 nm.

What Do The Result Means:

Normal values range from:

• Adults: 2.8 to 4.5 mg/dL
• Children: 4.0 to 7.0 mg/dL
