Below is a plain-language prep guide for the general health & wellness tests, including sample type and timing basics. General health and wellness tests are routine blood panels used to check broad markers of your overall health.

General Health & Wellness Tests: what it measures

Depending on which tests you choose, a general wellness panel can measure common blood markers related to blood counts, blood sugar, cholesterol and lipids, liver and kidney function, thyroid activity, and key vitamins or minerals. The exact set of markers depends on the panel selected, so review the test list before you order.

  • Blood counts
  • Blood sugar
  • Lipid panel
  • Liver function
  • Kidney function
  • Thyroid markers
  • Vitamins and minerals

Getting ready for the General Health & Wellness Tests

Preparation for general wellness blood testing is normally straightforward, and any needed timing or fasting window will be advised by the collection site. Follow the instructions given for the specific tests in your panel.

  1. Review the list of tests in your panel so you know what is being measured.
  2. Check whether any test in your panel requires fasting, and if so plan your appointment accordingly.
  3. Stay well hydrated in the days before your draw unless told otherwise.
  4. Avoid strenuous exercise and alcohol for a day before collection if the lab advises it.
  5. Take your usual medications unless the lab or your clinician tells you to hold them.
  6. Bring your test order or confirmation and a photo ID to the collection site.

Fasting, timing, sample type, and what to bring

Fasting

Some general wellness tests may need a fasting window while others do not, so fasting depends on the specific panel you order. If fasting applies, confirm with your lab.

Best time to collect

Many general wellness blood tests can be collected any time the lab is open, though morning appointments are common when fasting is required. The collection site will tell you the best window for your specific tests.

Sample type

Blood draw. The collector will explain the process before starting.

What to bring

  • 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
  • Your order confirmation email, in case the collection site asks to see it
  • 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
  • Water to drink before the draw and a light snack for afterward, if your test requires fasting

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.

The collection visit, step by step

A general wellness test involves a routine blood draw, usually from a vein in your arm, performed by a trained phlebotomist at a collection site. The sample is then sent to a lab for analysis, and the visit itself typically takes only a few minutes.

Details worth confirming with the collection lab before your visit:

  • Does my specific panel require fasting, and for how long?
  • What time of day should I schedule my collection?
  • When can I expect my results, and how will they be delivered?

When this test is useful

A clinician or wellness program may order general health testing to screen for common conditions, establish baseline values, or monitor trends over time. Because these panels are broad, they can help identify areas that may need a closer look.

Understanding your results

Reference ranges for general wellness markers vary by laboratory, by the method used, and by factors such as age and sex. Always interpret your results against the range printed on your own lab report rather than a general figure.

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 and what-to-bring details reflect the lab's published instructions, paraphrased into our own words. 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 a doctor's note or referral to order general wellness testing?

In most cases no referral or doctor's note is required, and you can order the tests you want online. Check the ordering requirements shown for the specific panel you select.

Do I have to fast for a general wellness panel?

It depends on which tests are included. Some markers require fasting and others do not, so follow the instructions for your panel and confirm with the collection lab.

How long do results take?

Turnaround is typically one to three business days after the sample is collected, though it can vary by lab and by test.

Can I take my medications before the blood draw?

In most cases you should take your usual medications unless the lab or your clinician advises otherwise. Ask the collection site if you are unsure about a specific medication.
