Many blood tests require specific preparation to ensure accurate results. Not following these guidelines can lead to misleading values and the need for repeat testing.
Fasting Tests
Tests requiring fasting include glucose (fasting), lipid profile, and some liver function tests. Fast for 8-12 hours before these tests. Water is permitted and encouraged.
Non-Fasting Tests
Tests like CBC, thyroid profile, and HbA1c typically do not require fasting. However, always confirm with your doctor or lab about specific preparation requirements.
Other Preparations
Some tests may require you to avoid certain medications, alcohol, or strenuous exercise before testing. Always inform your doctor about any medications you are taking.
