About this treatment
Vitamin A is essential for vision, immune function, reproduction, and cellular communication. Deficiency in Vitamin A can lead to serious health issues, including night blindness, an increased risk of infections, and xerophthalmia, which can lead to blindness if untreated. Conversely, excess vitamin A can cause toxicity, leading to symptoms like headache, dizziness, nausea, liver damage, and even death in severe cases. Testing helps to diagnose both deficiency and toxicity, allowing for appropriate treatment.

Who is this for?
Anyone wanting to check specific health markers. People monitoring known conditions or treatment effectiveness. Those who want targeted testing rather than a comprehensive panel. Individuals following up on previous abnormal results or investigating specific symptoms.
Preparation Required
Fasting for 10–12 hours before your appointment is recommended for accurate results (water is fine). Avoid alcohol for 24 hours and intense exercise for 12 hours before the blood draw. Morning appointments are ideal for consistent hormone and glucose readings. The blood draw typically takes 5–10 minutes.
