Understanding Lab Tests for Age-related Macular Degeneration
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Age-related macular degeneration (AMD) is a progressive eye condition that affects the central portion of the retina, leading to vision loss in older adults. AMD is primarily diagnosed through comprehensive eye examinations and imaging studies. While there is no blood test to directly diagnose AMD, laboratory testing plays a valuable supporting role in assessing nutritional factors that may influence disease progression.
Recommended Test
Zinc
This test measures zinc levels in the blood, which is crucial for eye health and retinal function. Research suggests that zinc supplementation may help slow the progression of age-related macular degeneration, and low zinc levels might be a risk factor for developing this condition. Monitoring zinc status can help guide appropriate supplementation strategies as part of comprehensive AMD management.

The Role of Blood Testing in AMD Management
Blood tests are fundamental for evaluating nutritional status and identifying deficiencies that may impact eye health. Research has shown that certain nutrients, particularly minerals like zinc, play important roles in retinal function and may influence the progression of macular degeneration. Testing can help guide nutritional interventions and supplementation strategies.
Understanding Your Results
Zinc testing results should be interpreted in the context of your overall health status and eye care plan. If zinc levels are found to be low, your healthcare provider may recommend dietary changes or supplementation. It's important to note that zinc supplementation should be monitored, as excessive levels can interfere with copper absorption and cause other health issues.
