Beta-Hydroxybutyric Acid
Also known as: B-OH
Use
The Beta-Hydroxybutyric Acid test aids in the evaluation of hyperinsulinemic hypoglycemia and the assessment of the etiology of anion gap acidosis. It is also used to screen for suspected mitochondrial disorders. This test is significant for diagnosing conditions associated with altered metabolic states and energy deficiencies, particularly in patients exhibiting symptoms related to imbalance in ketone bodies or certain metabolic disorders.
Special Instructions
Specimens should be processed in a timely manner following collection. Ensure accurate labeling and proper storage. Use ARUP's standard transport tube for transferring serum or plasma samples. Review specific specimen preparation detailed in the instructions to avoid sample rejection.
Limitations
This test's accuracy is contingent upon the proper collection and handling of specimens. Delayed processing or failure to maintain the sample within specified temperature ranges can lead to degradation of analytes, affecting the test results. Certain interfering substances or improper collection can cause discrepancies in measurements, and the test may not differentiate between sources of ketosis. Clinical correlation with other laboratory findings and patient history is essential for accurate interpretation.
