Phosphate Blood Test
Synonyms
Inorganic phosphate, blood
Purpose
The Phosphate Blood Test measures the concentration of phosphate ions in the blood. Phosphate is essential for building strong bones and teeth, producing energy, and supporting muscle and nerve function.
Maintaining a proper phosphate balance is crucial, as both high and low levels can indicate underlying health issues. This test is especially important for evaluating bone metabolism, kidney function, and parathyroid gland activity.
It is commonly performed alongside tests like calcium, parathyroid hormone (PTH), vitamin D, and renal function tests to provide a more complete picture of a patient’s metabolic and endocrine health.
Patient Preparation
No special preparations required.
Samples
1ml with a minimum volume of 0.7ml of serum or plasma collected in a Gel-barrier, red-top, or green top tube (lithium heparin). Avoid using EDTA, oxalate, or citrate plasma. Separate the serum or plasma within 45 minutes of sample collection. Store the sample at room temperature.
Reference Range
> 19 years 2.8-4.3mg/dL
Results Turnaround
Within 24 hours of receipt of samples.
Diseases / Diagnostic indicators
Abnormal phosphate levels in the blood can indicate various health conditions. High phosphate levels (hyperphosphatemia) may result from dehydration, intense exercise, or low blood volume (hypovolemia), and can also be linked to kidney dysfunction, where the body is unable to properly filter out excess phosphate.
On the other hand, low phosphate levels (hypophosphatemia) can occur due to the prolonged use of certain medications like antacids, diuretics, or steroids.
It may also be seen in malnutrition or conditions that affect nutrient absorption. These results help doctors identify and manage disorders related to bone health, kidney function, or hormonal imbalances.
