Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Acrodynia, also known as pink disease, is a rare condition primarily affecting children that is characterized by painful pink discoloration of the hands and feet, along with other symptoms like irritability, sweating, and sensitivity to light. This condition is directly caused by mercury poisoning, making laboratory testing essential for accurate diagnosis.
Recommended Test
Heavy Metals Panel, Random Urine
This comprehensive test measures mercury levels along with other heavy metals in the urine. High levels of mercury in urine directly confirm mercury poisoning, which is the underlying cause of acrodynia. This test is essential for diagnosing the condition and determining the severity of mercury exposure that leads to the characteristic pain and pink discoloration of the hands and feet.

Diagnosing Acrodynia (Pink Disease)
While the distinctive pink discoloration of extremities may suggest acrodynia, confirming the diagnosis requires laboratory evidence of elevated mercury levels in the body. Since mercury toxicity is the underlying cause of this condition, testing for mercury exposure is the definitive diagnostic approach.
Understanding the Connection
Mercury toxicity affects the nervous system and can cause the distinctive symptoms of acrodynia, including the characteristic pink coloration of extremities, pain, sweating, and behavioral changes. Early detection through urine testing is crucial for prompt treatment and prevention of long-term neurological complications.
Important Considerations
