Lab order online in Puerto Rico
A lab order online in Puerto Rico is the order the doctor gives you during your video visit so you can get tested at a lab near you: blood work, urine tests, strep tests, STI tests and more. You choose the lab. The order is included in your doctor visit, and reviewing the results is a US$49 follow-up visit for existing patients.

Lab order online in Puerto Rico: what it is
It's the same lab order you'd get at a doctor's office, after a video visit instead. Dr. Diana Nieves Castro, a Puerto Rico-licensed physician, evaluates you and, when a test would help diagnose or monitor something, gives you the order to take to the clinical lab closest to you.
We evaluate, diagnose and treat; a lab order is one more tool in your visit, for adults and children of all ages.

Which tests we order
The doctor orders the tests your situation calls for. The most common:
- Blood work: complete blood count, glucose and A1C, cholesterol and triglycerides, thyroid, kidney function, liver function, vitamin D and vitamin B12.
- Urinalysis and urine culture, for example when a UTI is suspected.
- Rapid strep test or throat culture for a sore throat.
- STI tests, with treatment if needed: see STI testing and treatment.
- HIV and hepatitis tests: read our guides to HIV testing and hepatitis testing.
- Other tests the doctor considers appropriate after evaluating you.

Price
The lab order is included in your US$79 doctor visit, at no extra charge. You pay the lab for the tests; if you want to use insurance for them, ask the lab.
Reviewing your results is a US$49 follow-up visit, for existing patients only. If your results show something that needs a full doctor visit, the doctor explains why and, only with your consent, you pay the difference. See the online follow-up visit.

When the doctor orders a lab test
Many problems can be diagnosed from your symptoms and what the doctor sees on camera. She gives you a lab order online when a test would help decide, for example:
- To confirm an infection, like strep throat, which can only be confirmed with a test, or a UTI in a young child or one that keeps coming back.
- To monitor a condition such as type 2 diabetes: the CDC notes most people with diabetes have an A1C test at least twice a year.
- To monitor a long-term medicine that calls for it.
- For preventive tests that fit your age and history.
You choose the lab
Use any clinical lab you like, anywhere in Puerto Rico. We have no agreements with any lab and take no money from labs, so we don't steer you to one.
Your results don't reach us automatically: ask the lab for them and bring them to your follow-up visit. Call the lab before you go to check hours, whether you need an appointment and what the tests cost.
When to go to the ER
Don't wait for a result if you have chest pain, trouble breathing, confusion, a fever with chills and back pain, or severe belly pain: call 911 or go to the nearest emergency room.
Book your visit
Book a visit and choose Doctor visit (US$79) if you need the doctor to evaluate you and order tests. If we've already seen you and you have your results, choose Follow-up visit (US$49).
How we care for you
We evaluate, diagnose and treat; if needed, we give you a lab order for a lab near you.
We see adults and children of all ages. Patients under 21: a parent with patria potestad (parental authority) or a legal guardian is on camera for the whole visit and shows photo ID.
Real-time video visit. We send you a secure video link. It works on your phone, tablet or computer.
If appropriate, the doctor prescribes and we send your prescription to your pharmacy. We do not prescribe controlled substances.
You must be physically in Puerto Rico during the visit (visitors, tourists and cruise passengers are welcome).
In an emergency, call 911.
