Get Same Day Lab Results: What Is Realistically Possible
A same day lab result is released to the patient or ordering clinician on the calendar day the specimen is collected, and same day lab results are achievable for a defined group of tests, not everything a lab can run. At Avista Medical Center, we run blood draws and basic diagnostic testing in our own office, removing the courier step that causes most delays.
The phrase is used loosely: a rapid strep swab and a complete blood count can come back within hours, while a thyroid or hormone panel usually cannot.
Below, we break down which tests realistically return the same day, what speeds up or slows down processing, and how to arrange fast results.
Same-day results depend less on the lab’s speed than on where the specimen is processed. Testing drawn and run in the same building almost always beats testing that has to be shipped out.
Which Tests Can Return the Same Day
Tests run on-site with a benchtop analyzer are the ones that come back fastest. These are typically:
- Complete blood count (CBC) – red and white cells, hemoglobin, platelets
- Electrolyte panel – sodium, potassium, chloride, bicarbonate
- Basic metabolic panel – glucose, kidney function, calcium
This is point-of-care testing: the specimen never leaves the building, so the result is available while you are still in the office or shortly after.
CDC information on point-of-care and rapid testing
Tests That Usually Take 24 to 72 Hours
Send-out testing goes to an outside reference laboratory, and transit time is built into the result. Common examples:
- Thyroid panels (TSH, free T3, free T4)
- Hormone panels, including testosterone and estradiol
- Lipid panels and advanced cardiac markers
Expect 24 to 48 hours, occasionally 48 to 72 hours if the draw happens late in the day or on a Friday. A specimen collected Friday afternoon may not be processed until Monday.
Blood Test Turnaround Time: What Speeds It Up or Slows It Down
Order clarity. A vague order gets flagged for clarification. A precise order with the correct test panel codes moves straight through.
Draw timing. Morning draws enter the processing queue earlier. Afternoon draws often wait until the next run.
Specimen quality. A hemolyzed sample, where red blood cells have broken open, cannot be used for some tests and requires a repeat draw.
A repeat draw is the most avoidable delay in lab testing. Fasting when you were not told to fast, or eating when you were, can invalidate a specimen and push your result back by days.
On-Site Lab vs. Off-Site Processing
The difference between on-site and off-site processing is hours versus days.
An on-site (in-house) lab draws and analyzes the sample in the same facility.
Off-site processing ships the specimen to a reference laboratory, adding courier time on both ends plus that lab’s queue.
For routine monitoring, on-site is faster. For specialized testing requiring equipment a smaller practice lacks, off-site is the only option.

Step-by-Step: How to Arrange Same-Day Lab Results
Arranging same-day results is mostly about removing the steps that cause waiting. Here is the sequence.
- Confirm the test can be run on-site. Ask: “Is this test processed in your lab or sent out?” If it is sent out, same-day is off the table.
- Get the order written before you arrive. A lab order (referral or requisition) must exist before the draw; walk-in testing without one usually means a second visit.
- Book the earliest appointment slot available. Morning appointments enter the processing queue first.
- Ask about STAT or priority handling. With a clinical reason to expedite, this flag can move your specimen to the front.
- Confirm how results will reach you. Portal, phone call, or in-person review.
- Verify the turnaround time in writing. A printed or portal-visible estimate gives you something to follow up against.
What You’ll Need Before You Go
- A valid lab order from a licensed clinician
- Photo identification
- Your insurance card, or a method of payment if you are paying directly
Ask the front desk to confirm your order is in the system before you drive over. Orders that were faxed and never entered are a routine cause of a wasted trip.
Fasting Blood Test Preparation: How to Avoid a Repeat Draw
Fasting blood test preparation comes down to three things: the right window, the right intake, and the right disclosure.
A typical fasting window is 8 to 12 hours before the draw.
Tell the phlebotomist about every medication and supplement you take, including over-the-counter items, since some affect results directly and others affect how the sample behaves.
If you accidentally ate, say so at check-in. A rescheduled draw costs one morning; an inaccurate result can cost a wrong clinical decision.

How to Get Blood Test Results Online and Through Your Patient Portal
Getting blood test results online is now the default at most practices, usually through a patient portal. Results appear once verified and released, typically after the clinician reviews them.
What to expect:
Schedule with Dr. Punya Raman →
- Portal release. Most results post within the turnaround window for that test.
- Clinician review. Some practices hold results until the clinician signs off, adding a day.
- Notification. You may get an email or text when a result is available.
If a result looks abnormal in the portal, do not act on it alone. Ask for a review; a single out-of-range value is often not meaningful without context.
Cost, Insurance, and Ordering Requirements for Fast Lab Results
Cost and ordering requirements trip up more patients than turnaround time does, so sort them out before the draw.
Insurance coverage. When a test is covered, you typically owe your plan’s cost-sharing: a copay, coinsurance, or a deductible amount. Two variables change what you pay:
- In-network vs. out-of-network. A lab that is out-of-network can bill you at a higher rate even when the test itself is covered.
- Preventive vs. diagnostic. Some routine screenings are covered at no cost-sharing when they are ordered for preventive reasons, but the same test ordered to investigate a symptom may be billed as diagnostic with cost-sharing attached.
Self-pay pricing. Cash-pay pricing is often lower than the billed rate for the same test and removes the insurance paperwork step.
What to ask before you commit. These five questions resolve most billing surprises:
| Question to Ask | Why It Matters | What a Good Answer Sounds Like |
|---|---|---|
| Is this test run on-site? | Determines whether same-day is possible | A direct yes or no, with the test named |
| What is the turnaround time? | Sets your expectation | A specific window, not “soon” |
| What is the self-pay price? | Avoids surprise billing | A figure given before the draw |
| Is this lab in my insurance network? | Changes your cost-sharing | A clear in-network or out-of-network answer |
| How will I get results? | Prevents phone tag | Portal, call, or visit, named clearly |
Membership models. Some practices bundle routine labs into a membership, spreading cost across the year and removing per-test pricing decisions.
We do not publish per-test pricing because it depends on the specific panel ordered.
Ask for the price in writing, including the collection fee if one applies. A quoted test price sometimes excludes the draw itself.

What to Do When Results Are Delayed or Abnormal
Most pages stop at turnaround times and never explain what happens when a result does not arrive on schedule or comes back out of range. That is the gap this section fills.
When Results Are Delayed
Delayed results are usually a logistics problem, not a clinical one. Check three things:
- Was the specimen sent out? Send-out testing adds courier time on both ends plus the reference lab’s queue.
- When was the draw? A specimen collected late in the day or on a Friday may not enter processing until the next business day.
- Was a repeat draw ordered? A hemolyzed sample or mis-timed fasting draw can require a second collection, resetting the clock.
If the delay passes the expected window, call the office and ask for the order status. Most labs can trace a specimen by the accession number on your requisition. Ask: has the specimen been received, is it in process, and has the result been released to the ordering clinician? Knowing which stage you are in tells you whether to wait or escalate.
If a result is marked critical or urgent, the lab is required to notify the ordering clinician directly rather than waiting for a routine release. If you were told a result was critical and you have not heard from anyone, call the office immediately.
When Results Are Abnormal
An out-of-range value is a signal to review, not a diagnosis. Some abnormal results are expected and stable, especially for patients on medication titrated against a lab value.
A useful way to think about it:
- Slightly out of range, no symptoms. Often warrants a repeat test to confirm the value is real and not a lab artifact.
- Clearly out of range, no symptoms. Usually warrants clinician review and possibly additional testing to find the cause.
- Out of range with symptoms. Raise this with your clinician promptly rather than waiting for routine follow-up.
Do not search the value, decide what it means, and act on that alone. Reference ranges are built for a population, not for you: age, sex, pregnancy, medications, hydration, and time of day all shift what counts as normal.
How to Prepare for the Follow-Up Conversation
Bring three things to your clinician: the result, the reference range printed next to it, and a list of anything that changed since your last test, including new medications, supplements, diet changes, or illness. Ask what the value means in the context of your history, whether a repeat test is warranted, and what would prompt a change in treatment.
A single abnormal value rarely tells the whole story. The pattern across several results, tracked over time, is what guides a decision.

Conclusion: Getting Same-Day Lab Results Without the Guesswork
The gap between a fast result and a slow one usually comes down to whether the specimen stays in the building. Ask that question first, and most of the uncertainty disappears.
At Avista Medical Center, we handle blood draws and routine diagnostics in-house, which means many routine tests come back the same day and most others land within 24 to 72 hours. Patients also get access to affordable pharmacy services and comprehensive medical memberships that fold routine labs into one predictable cost.
Schedule with Dr. Punya Raman and get your lab work drawn, run, and explained without the runaround.
Frequently Asked Questions
Can you get same-day lab results?
Yes, for certain tests. Rapid tests like a COVID test, flu test, strep test, urinalysis, or a basic metabolic panel can return within 15 minutes to a few hours when processed on-site with point-of-care testing. Routine blood work such as a complete blood count or electrolyte panel often takes 24 to 48 hours because it requires a full laboratory run. Ask your provider which tests qualify for same-day processing before your visit.
Which blood tests can have same-day results?
Tests that use point-of-care analyzers or in-house lab equipment can often return the same day. These include a complete blood count (CBC), basic metabolic panel, urinalysis, rapid strep, influenza, COVID PCR test, and pregnancy test. More specialized tests like hormone panels, thyroid antibodies, or cultures are usually sent to an off-site lab and take 48 to 72 hours or longer. Always confirm the expected turnaround time when the order is placed.
How long do routine blood test results take?
Most routine blood work, including a complete blood count, electrolyte panel, and lipid panel, takes 24 to 48 hours when processed at an on-site lab. If the specimen is sent to an off-site reference laboratory, expect 48 to 72 hours, and sometimes longer for specialized testing. Factors like weekends, holidays, and whether the test requires a fasting sample can extend the timeline. Your provider’s office can give you a specific estimate for each test ordered.
How will I receive my lab results?
Most practices release results through a secure patient portal, where you can view them online once a clinician has reviewed them. Some offices also call with urgent or abnormal findings. You may request a printed copy or have results sent to another provider. Ask about the practice’s result delivery process before your blood draw so you know where and when to look. If you do not see results within the expected window, call the office to follow up.
