Waiting two to three days for lab results is standard when a blood sample gets sent out to an external laboratory, but it is not the only option. On-site labs at primary care offices can process many common tests directly, cutting that wait down to minutes or hours rather than days.

Elevate Health Group runs a full on-site laboratory at each of our three Los Angeles area locations, which changes the timeline significantly for most routine testing.

On-Site Lab Testing vs Sending Samples Out

Testing TypeTypical Turnaround
On-site rapid tests (glucose, strep, pregnancy)15 to 30 minutes
On-site comprehensive panels (CBC, metabolic panel, lipid profile)1 to 2 hours
Tests sent to an external reference laboratory24 to 48 hours or longer

The difference comes down to where the sample is actually processed. On-site labs use equipment at the point of care, while external labs require shipping the sample to a separate facility, which adds the majority of the wait time.

What Tests Are Available for Same-Day Results

A wide range of common tests can be processed on-site, including complete blood counts, basic and comprehensive metabolic panels, lipid profiles, liver and kidney function tests, thyroid panels, hemoglobin A1C, urinalysis, pregnancy tests, and rapid infectious disease screenings such as strep and influenza. More specialized or less common tests may still require sending a sample to an outside laboratory.

Do You Need to Prepare for Same-Day Testing?

Preparation depends on the specific test. Fasting for eight to twelve hours is typically required for comprehensive metabolic panels, lipid profiles, and glucose tolerance testing, while complete blood counts, thyroid panels, and most routine tests do not require fasting. Your provider will give you specific instructions when your test is ordered.

Accuracy: Is On-Site Testing as Reliable as External Labs?

On-site laboratories that maintain proper accreditation and quality control standards provide results with the same accuracy as external reference labs. The primary advantage of on-site testing is speed and convenience, not a tradeoff in reliability, since the equipment undergoes the same calibration and quality assurance processes.

When Same-Day Results Matter Most

Fast turnaround is particularly valuable for time-sensitive treatment decisions, such as confirming an infection before starting antibiotics, checking blood sugar during a diabetes management visit, or reviewing bloodwork as part of a same-day sick visit rather than waiting days to adjust treatment.

Where to Get Same-Day Blood Testing in Los Angeles

On-site lab testing is available at our Glendale, Burbank, and La Cañada offices, and is also built into our pre-surgery checkup and adult physical exam services.

Frequently Asked Questions

Which blood tests are available the same day?

Many routine tests, including complete blood counts, metabolic panels, lipid profiles, thyroid panels, and A1C testing, can be processed on-site within one to two hours. Rapid point-of-care tests like glucose checks are available even faster.

Do I need an appointment for same-day blood work?

Yes, blood work is typically ordered as part of a scheduled visit with your provider, though same-week appointments are generally available across our three locations.

Is same-day testing more expensive than sending a sample to an outside lab?

On-site testing is generally billed the same way as standard lab work through your insurance, without an added cost simply for faster turnaround.

What if my test requires specialized processing not available on-site?

Some specialized tests still require sending a sample to an outside reference laboratory, in which case standard turnaround times of 24 to 48 hours or longer typically apply.
