A critical value for sodium indicates a blood sodium level that is dangerously low or high and requires immediate medical attention. According to the Critical Value Chart from Laboratory Alliance of Central New York, LLC, the critical values for sodium are less than 120 mmol/L or greater than 160 mmol/L.
Understanding Sodium Critical Values
Critical values are laboratory results that fall significantly outside the normal range and signify a potentially life-threatening condition. For sodium, these values highlight severe electrolyte imbalances, which can have profound effects on the body's functions.
A sodium level:
- Below 120 mmol/L is considered critically low (hyponatremia).
- Above 160 mmol/L is considered critically high (hypernatremia).
These ranges are specifically for adult chemistry testing, as indicated in the reference.
Why Are Critical Values Important?
Recognizing and promptly addressing critical values is crucial for patient safety. When a laboratory identifies a critical value, they typically alert the healthcare provider immediately, enabling timely intervention to prevent serious complications or adverse outcomes.
Critical Value for Sodium
The precise critical value for sodium, as outlined in the Critical Value Chart by Laboratory Alliance of Central New York, LLC, is summarized in the table below:
| Test | Critical Value |
|---|---|
| Sodium | <120 and >160 mmol/L |
This indicates that both severe hyponatremia (low sodium) and severe hypernatremia (high sodium) are considered critical conditions.
