Clinical Chemistry

Osmolality measurement is a low-cost, high-value clinical tool in the diagnosis of and patient management for a variety of conditions.

Osmolality testing enables hospitals to increase quality of patient care while reducing costs

Osmolality is a quick and effective test to help:

  • Evaluate the body’s water balance and its ability to produce and concentrate urine
  • Investigate low sodium levels (hyponatremia)
  • Detect the presence of toxins in the body
  • Monitor the electrolyte balance of patients receiving osmotically active drug therapies (e.g. mannitol used to treat cerebral edema)
  • And, more

It can also help monitor the effectiveness of a treatment or a condition found to be adversely affecting a person’s osmolality.

Importance of Measured Osmolality

Direct measurement of body fluid osmolality with a freezing point depression osmometer is the preferred method when reporting osmolality in a clinical setting1.

In practice, physicians use both measured and calculated osmolality to determine a patient’s osmolal gap. The difference between measured and calculated osmolality can be diagnostically significant for conditions such as toxic alcohol ingestion, and useful for monitoring patients being treated with osmotically active therapies.

If a laboratory were to solely provide calculated osmolality physicians could not calculate the osmolal gap to screen for foreign substances.

The Value of STAT Osmolality Testing

Advanced Instruments products use the gold-standard freezing point depression method to ensure accurate results for confident reporting. We offer a variety of clinical osmometers to meet your sample throughput and automation needs and ensure you are ready for the quick turnaround needed for high-value STAT testing. Better for the patient; better for you.

The Value of Our Clinical Osmometers

Our portfolio of osmometers deliver the ease-of-use features demanded by labs to ensure they stay productive. Easily integrated into any lab workflow, our instruments offer the level of automation needed to ensure maximum productivity, so labs can handle any level of sample testing in an efficient manner. With increasing levels of staff shortages and continued challenges this is of utmost importance.

User-Friendly Features
