Vitamin A

Experiencing vision changes, frequent infections, or skin issues and want assessment of vitamin A status for optimal health and immune function?

Overview

The Vitamin A test measures the level of this essential vitamin in your blood, acting like a health check for your body's "night vision goggles" and immune system armor. Vitamin A is your body's multitasking hero – it helps your eyes see clearly in dim light, keeps your immune system strong to fight off infections, and ensures your skin and cells grow and repair properly. When your vitamin A levels are off balance, you might experience problems like difficulty seeing at night, getting sick more often, slow wound healing, or skin issues.

This test is particularly helpful if you're dealing with vision problems, frequent infections, or have conditions that affect how your body absorbs nutrients from food. It's also valuable for anyone taking vitamin A supplements, since too much can be just as problematic as too little. By checking your vitamin A status, you and your healthcare provider can determine if you need to adjust your diet, modify supplements, or address any underlying issues that might be affecting your body's ability to maintain healthy vitamin A levels.
