A General Health & Wellness Testing is usually quick, and most of the work is in the preparation: timing, fasting, and a short checklist. General health and wellness testing uses a blood sample to give a broad picture of your overall health.
What the General Health & Wellness Testing measures
Depending on the panel ordered, general wellness testing may measure things like blood cell counts, blood sugar, cholesterol and other lipids, kidney and liver markers, and electrolyte levels. It can also include thyroid or nutrient markers on some panels. Your specific panel determines which measurements are included.
- Blood cell counts
- Blood sugar
- Lipid profile
- Kidney markers
- Liver markers
- Electrolytes
- Thyroid markers
General Health & Wellness Testing prep, step by step
In most cases nothing extra is needed before this test. Ask the testing location about any timing or fasting instructions before your visit.
- Confirm with the lab whether fasting is required for your specific panel.
- If fasting is needed, plan to skip food and caloric drinks for the instructed window, usually overnight.
- Drink water normally unless the lab tells you otherwise.
- Take your regular medications as directed unless the lab or your clinician says to hold them.
- Avoid strenuous exercise right before the draw if the lab advises it.
- Bring your order or requisition and a photo ID to the appointment.
Fasting, timing, sample type, and what to bring
Fasting
Some panels, especially those including glucose or lipids, may ask for fasting, while others need no fasting at all. Because requirements differ by panel, confirm with your lab.
Best time to collect
Morning appointments are common because they make an overnight fast easier if one is required. Otherwise, you can usually collect the sample whenever the lab has an opening.
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
- 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.
At the collection site
A trained phlebotomist cleans an arm vein and draws a small tube or two of blood, which usually takes only a few minutes. The sample is sent to a lab for analysis, and you can return to your normal routine right away.
Details worth confirming with the collection lab before your visit:
- Does my specific panel require fasting?
- How long before the draw should I fast if needed?
- Should I take my medications as usual on the day of the test?
Why a clinician may order this test
A clinician may order general wellness testing during a routine visit to check overall health or to monitor a known condition. It can also be used to look for early signs of problems before symptoms appear.
Your results and next steps
Reference ranges vary by laboratory, so a value flagged outside the range on one report may not be flagged on another. Your clinician interprets your results alongside your history and other findings.
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 to fast for general wellness testing?
It depends on which measurements are included. Some panels require fasting and others do not, so ask the lab about your specific order before your visit.
How long does the appointment take?
The blood draw itself usually takes only a few minutes, though you may spend a bit longer checking in and waiting.
When will my results be ready?
Turnaround is commonly one to three business days, but timing can vary by lab and by the tests included.
Can I exercise before the test?
Strenuous activity can affect some measurements, so ask the lab whether you should avoid it beforehand.
