- Blood glucose levels: Elevated blood glucose levels are a hallmark of DKA. In most cases, blood glucose levels exceed 250 mg/dL.
- Arterial blood gas (ABG) analysis: ABG analysis provides insights into acid-base imbalances in DKA. It helps measure blood pH, bicarbonate levels, and oxygenation status.
- Anion gap: The anion gap is an important diagnostic tool in DKA. It measures the difference between the positively charged ions (cations) and negatively charged ions (anions) in the blood. In DKA, the anion gap is typically elevated due to the presence of ketone bodies and unmeasured anions. An increased anion gap helps confirm the diagnosis of DKA and assess its severity.
- Electrolyte levels: DKA can cause electrolyte imbalances, such as low levels of potassium and sodium. Measuring these electrolyte levels helps guide appropriate management.
- Ketone bodies: Ketone bodies, such as beta-hydroxybutyrate and acetoacetate, are by-products of fat metabolism. Measuring ketone levels in the blood or urine can help confirm the presence of DKA.
These laboratory tests, combined with clinical examination findings, enable healthcare professionals to accurately diagnose DKA and determine the appropriate course of treatment. Early detection and intervention are crucial in preventing complications and ensuring positive patient outcomes.
