This page explains how to prepare for a Online Liver Function Test (LFT Test) in Radisson, NY, what the test measures, and what to confirm with the collection lab. A liver function test is a common blood panel used to see how well the liver is working and to assess its overall health.

- Albumin
- Liver enzymes
- Liver function markers
Preparation checklist for the Online Liver Function Test (LFT Test)
Most patients require no special preparation for this blood test. Still, recheck timing or fasting requirements with the testing location before you go.
- Confirm with the collection lab whether any fasting is required for your specific order.
- Ask the lab whether your appointment should be in the morning or at another preferred time.
- Drink water beforehand unless the lab tells you otherwise, since hydration can make the draw easier.
- Tell the phlebotomist about any medications, supplements, or herbal products you take, as some can affect liver results.
- Bring your test order or requisition and a photo ID to the appointment.
- Avoid alcohol in the days before the draw if your clinician has advised it, and ask the lab about any other restrictions.
Fasting, timing, sample type, and what to bring
Fasting
Many people do not need to fast for a liver function test, but fasting requirements depend on the specific panel and your clinician's instructions. Confirm with your lab whether you should fast and for how long.
Best time to collect
This test can usually be collected at any time your lab offers appointments, though some clinicians prefer a morning draw. Results typically take about 1 to 3 business days, so ask the lab when your results are expected.
Sample type
Blood draw. The collector will explain the process before starting.
What to bring
- Your order confirmation email, in case the collection site asks to see it
- Your printed lab order or requisition form — the ordering physician prepares it for you after you order, and you print it (or fax it from your account) before visiting
- Water to drink before the draw and a light snack for afterward, if your test requires fasting
- A government-issued photo ID (most collection sites verify identity at check-in)
- A written list of the medications and supplements you currently take
- A short-sleeved or loose-sleeved shirt for an easy blood draw
You do not need an insurance card or a payment method at the collection site: the lab does not bill insurance, and you pay at order time, so there is no copay or deductible. The lab also provides the physician's requisition, so you do not need a separate doctor's referral.
Order process and what-to-bring details reflect the lab's published instructions, paraphrased in our own words. Confirm final requirements with the collection lab that will perform your draw.
What the collection involves
A trained phlebotomist cleans an area on your arm and inserts a small needle into a vein to collect a blood sample into a tube. The draw usually takes only a few minutes, and you can generally resume normal activities right away.
Details worth confirming with the collection lab before your visit:
- Does my specific order require fasting, and for how long?
- What time of day should I schedule the blood draw?
- When should I expect my results, and how will they be shared with me?
Why a clinician may order this test
A clinician may order this panel as part of a routine checkup, to monitor a known liver condition, or to investigate symptoms that could relate to liver health. It can also be used to follow up on abnormal results from an earlier test.
What results mean
Reference ranges for the markers in this panel vary from one laboratory to another, so your report's ranges are the ones that apply to you. Your clinician will interpret your results in the context of your history, medications, and other findings.
Preparing in Radisson
In Radisson, collection sites vary in hours and walk-in policies. Book or confirm ahead when you can, especially for a morning fasting draw.
General test information is compiled from publicly available reference material, including MedlinePlus (medlineplus.gov) and the Centers for Disease Control and Prevention (cdc.gov), and is reviewed for clarity.

Preparation instructions, timing, and pricing vary by collection lab — always confirm them with the lab that will perform your draw.
Common questions
Frequently asked questions
Do I need to fast for a liver function test?
Not always. Many patients require no special preparation, but fasting rules depend on the exact panel and your clinician's instructions, so check with the collection lab before your appointment.
How long does the blood draw take?
The collection itself usually takes only a few minutes, though you may spend additional time checking in and waiting at the lab.
When will my results be ready?
Turnaround is typically about 1 to 3 business days, but this can vary by lab and by how the sample is processed. The lab can give you a more specific estimate.
Can my medications affect the results?
Some medications, supplements, and herbal products can influence liver-related markers. Tell your clinician and the phlebotomist what you take so your results can be interpreted accurately.
