Normal Values and Clinical Significance of Sodium in EFP






Emission Flame Photometry

Emission flame spectrophomter is used to several electrolytes like sodium and potassium measure through the principle of spectrophotmetry. Likewise, we have several range of values that we follow to be able to interpret results and correlate it to possible conditions.

Normal Values for Sodium

Normal= 135 mmol/l or Range between 136-146 mmol/l

Hypernatremia= > or = 150 mmol/l
Hyponatremia= < 130 mmol/l

Gestating Parents
From Week 35-38 137 mmol/l or Range between 134-140 mmol/l
From Week 27-30 136 mmo;/l or RAnge between 134-138 mmol/l
From Week 15-18 135 mmol/l or Range between 132-139 mmol/l

Clinical Significance:

Sodium plays a vital role in our system that aids primarily in water balance inside the bode and also inside and outside the cell being called as the major extracellular cation component. Nerve impulses also are made possible by the electrostatic charge made by the sodium and potassium mechanism. Thereby, an imbalance of the sodium content of a cell or a system as whole can be an affect not only to the cell but also to other elctrolytes that are related to it.

Hypernatremia- an increase in one's sodium content

Common causes:
1. loss of thirst respones
2. diabetes insipidus (defective renal concentrating mechanism)
3. loss of free water from other sources
4. High Sodium intake
5. diarrhea
6. nephrotic syndrome

Hyponatremia- a decrease in one's sodium content

Common cause:
1. excessive water accumulation
2. diarrhea
3. vomiting
4. syndrome of inappropriate antidiuretic hormone
5. acidosis
6. salt-losing nephritis
