How do I need to prepare for my lab tests?
Preparing for your lab test depends on the type of test ordered, but in most cases, your DrHouse physician or Labcorp will provide specific instructions. Common preparation steps may include fasting, avoiding certain medications, or scheduling your test at a particular time.
Quick Answer
- Follow any instructions given by your DrHouse physician
- Some tests require fasting (8–12 hours)
- Bring your lab referral and a valid ID
- Stay hydrated unless told otherwise
- Check if your test has special timing or restrictions
General Preparation Guidelines
Before going to your Labcorp appointment, it’s important to understand whether your test has any special requirements.
Common preparation steps include:
- Fasting: Some blood tests (like glucose or cholesterol panels) require no food or drink except water for 8–12 hours
- Medications: You may be asked to pause certain medications—but only if your doctor instructs you to do so
- Hydration: Drinking water can make blood draws easier unless you’re told otherwise
- Timing: Some tests must be done at specific times of day (e.g., morning hormone tests)
Always follow the exact instructions provided during your visit, as requirements vary by test.
What to Bring
When you go to the lab, make sure you have:
- Your lab referral from DrHouse
- A valid photo ID
- Your insurance information (if applicable)
This helps ensure your test is processed without delays.
At the Lab
Most lab visits are quick and straightforward. A technician will collect your sample (such as blood or urine), and you can leave shortly after.
Try to:
- Wear comfortable clothing (short sleeves for blood draws)
- Arrive on time if you booked an appointment
- Allow a little extra time in case of wait times
Limitations and What to Know
- Preparation instructions vary by test—not all tests require fasting
- If instructions are unclear, you may need to confirm before your visit
- Not following prep instructions could affect your results or require retesting
- Some specialized tests may have additional requirements
