Understanding Lab Tests for Reye's Syndrome
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Reye's syndrome is a rare but serious condition that causes swelling in the liver and brain, primarily affecting children and teenagers recovering from viral infections. While there is no single blood test to diagnose Reye's syndrome itself, blood testing is fundamental for monitoring the body's response and assessing complications associated with this condition.
Recommended Test
Ammonia, Plasma
This test measures ammonia levels in the blood, which can become significantly elevated in Reye's syndrome due to liver damage. Monitoring ammonia levels is essential because high concentrations can be toxic to the brain and may contribute to the neurological symptoms associated with this condition. Regular monitoring helps guide treatment decisions and assess the severity of liver involvement.

Why Blood Testing is Critical in Reye's Syndrome
Reye's syndrome diagnosis is typically based on clinical symptoms and medical history, particularly following aspirin use during viral illness. However, blood tests play a crucial role in monitoring liver function and detecting metabolic complications that can occur with this condition, helping healthcare providers manage treatment and assess severity.
Understanding the Test Results
Elevated ammonia levels in patients with suspected Reye's syndrome can indicate liver dysfunction and help healthcare providers assess the severity of the condition. This information is vital for determining appropriate treatment strategies and monitoring the patient's response to therapy.
