How to Schedule an Appointment at Honolulu Diagnostic Lab Services Inc
Getting an appointment at Honolulu Diagnostic Lab Services Inc
Honolulu Diagnostic Lab Services Inc is a private laboratory in Honolulu that draws blood and processes lab tests ordered by your doctor. To schedule an appointment, you'll need to call their main line or visit in person — they do not take appointments online. Have your doctor's lab order ready when you contact them, as they'll need the test codes and your insurance information.
The lab is located on Oahu and serves patients who have been referred by their physician. Unlike some larger chains, Honolulu Diagnostic operates as a local provider, which means their hours and availability are set by their own schedule, not a national system. Calling ahead is the most reliable way to confirm they can perform your specific tests and to find out how soon they can see you.
Key Takeaways
- Call Honolulu Diagnostic Lab Services Inc directly to schedule — they do not take online appointments.
- Bring your doctor's lab order, insurance card, and photo ID to your appointment.
- The appointment itself usually takes 10 to 15 minutes for blood draw and basic paperwork.
- Results are typically available within one to three business days, depending on the test type.
- If you don't have a doctor's order, ask whether the lab offers walk-in testing or direct-to-consumer options.
What to bring and how to prepare
Bring your insurance card, a photo ID, and the lab order your doctor gave you. The order should list the specific tests needed — if you're unsure what tests you're having done, call the lab ahead of time and they can tell you based on the order code. Some tests require fasting (not eating or drinking anything but water for 8 to 12 hours before the draw), so ask when you schedule whether that applies to you.
Wear loose, comfortable clothing with sleeves that roll up easily — the phlebotomist will need access to your arm. If you have a history of difficult veins or tend to feel faint during blood draws, mention this when you call to schedule. The lab staff can note it in your file and may ask you to sit for a few minutes after the draw.
What happens during your visit
When you arrive, check in at the front desk with your ID and insurance card. You'll fill out a brief form confirming your contact information and medical history if it's your first visit. The phlebotomist will call you back to a draw station, verify your name and date of birth, and explain what they're about to do.
The actual blood draw takes just a few minutes. The phlebotomist will tie a band around your upper arm to make the vein more visible, clean the area with an alcohol wipe, and insert a needle to collect the sample into labeled tubes. You may feel a pinch but it's usually quick. After the draw, they'll apply pressure and a bandage. Most people can leave immediately and return to normal activities, though some tests have specific post-draw instructions.
How to find their contact information
Honolulu Diagnostic Lab Services Inc operates in Honolulu on the island of Oahu. To find their current phone number and exact address, search online for "Honolulu Diagnostic Lab Services Inc" or ask your doctor's office — they often have the lab's contact details on file and may even call to schedule for you.
Your doctor's office may also have a preferred lab they work with regularly. If you're unsure whether to use Honolulu Diagnostic or another lab, ask your doctor whether your insurance covers both and whether one has faster turnaround times for your specific tests.
Understanding your test results
Results are usually ready within one to three business days. The lab will either mail them to your doctor's office, send them electronically, or call you directly — ask which method they use when you schedule. Your doctor will review the results and contact you to discuss what they mean and whether any follow-up is needed.
Results come with a reference range — the normal values for that test. Your result will show whether it falls within that range, is slightly high or low, or is significantly outside normal limits. Your doctor interprets these numbers in the context of your health history and symptoms, so don't assume a result is abnormal just because it's outside the range. Some people naturally fall slightly outside the range and that's fine; others need follow-up testing or treatment.
What to do if you can't keep your appointment
If you need to reschedule, call the lab as soon as you know you can't make it. Most labs appreciate at least a few hours' notice, though they understand that emergencies happen. When you call to reschedule, confirm whether any fasting or other preparation still applies to your new appointment time.
If your doctor's order expires before you can get in, ask your doctor's office to send a new one. Lab orders are usually valid for 30 days, but this varies by test type and insurance. Your doctor can reissue an order quickly if needed.
Frequently Asked Questions
Do I need a doctor's order to get blood work done?
Most labs, including private ones, require a doctor's order to draw blood. Some labs offer direct-to-consumer testing where you can order tests yourself without a doctor, but this is less common. Call Honolulu Diagnostic and ask whether they offer this option if you don't have a doctor's order yet.
How long does the appointment actually take?
The blood draw itself takes 5 to 10 minutes. Add 5 to 10 minutes for check-in and paperwork. Plan for 20 to 30 minutes total from arrival to leaving, though it's often faster. If the lab is busy, you may wait longer.
Can I eat or drink before my appointment?
It depends on the test. Some tests require fasting (nothing but water for 8 to 12 hours before), while others don't. Ask when you schedule. If you're unsure and eat anyway, tell the phlebotomist — they'll note it on your results so your doctor knows.
What if I'm nervous about needles?
Tell the lab staff when you arrive. They can let you lie down during the draw, have you look away, or give you a few minutes to calm down first. Fainting during blood draws is rare but not unheard of, and the staff is trained to handle it. Taking slow, deep breaths before and during the draw helps.
When will I get my results?
Most routine blood work is ready within one to three business days. Some tests take longer — ask when you schedule. Results go to your doctor first, and your doctor will contact you. If you haven't heard anything after a week, call your doctor's office to check.
