Preparation requirements vary depending on the specific test parameters. For most blood-based diagnostic tests, fasting for 8 to 12 hours (no food or drink except water) is recommended. Please consult your physician or contact our support team for exact guidelines.

This test measures specific chemical compounds, cellular structures, or hormonal levels in your sample to provide diagnostic indicators for metabolic or systemic health.
Most routine test results are processed and delivered securely to you within 24 to 48 hours from the time of sample collection.
Fasting guidelines depend on the individual biomarkers. It is highly recommended to confirm the requirements with the lab coordinator when booking.
