Medical tests in Buenos Aires for travelers & expats

Getting a blood test in a new country sounds complicated, but in Buenos Aires it is surprisingly simple — often faster and far cheaper than back home. This guide explains how to do it well as a traveler, digital nomad or new expat: what you can test, whether you need a doctor's order, how long results take, and how to tell a real accredited laboratory from a booking platform that simply resells one.

Can I get tested without insurance or a doctor's order?

In most cases, yes. As a private (particular) patient you do not need local health insurance, residency or a national ID — a passport is enough for identification. You pay a published price and your results are delivered to a secure online portal.

A doctor's order is also optional for a wide range of studies. At Laboratorio Aclimu you can book and pay privately, with no prescription, for things like:

• Sexual health panels — HIV, syphilis, hepatitis B and C, and more
• Pregnancy blood tests (quantitative β-hCG)
• Thyroid profile (TSH, Free T4, Free T3)
• Routine check-ups — blood count, glucose, cholesterol and triglycerides, liver and kidney function
• Vitamin and iron status (ferritin, vitamin D, vitamin B12)
• Travel-related testing, such as dengue

Tests that you want billed to an Argentine insurer or prepaga are the exception: those still require a medical order and prior authorisation.

How fast are the results?

Turnaround is one of the reasons testing in Buenos Aires is so convenient for travelers:

Type of test	Typical turnaround
Routine blood work (CBC, glucose, lipids, liver, kidney)	24–48 business hours
Molecular tests by PCR	48–72 hours
Genetic and genomic studies	Per protocol (ask when booking)

Results are published to an online portal, so you can open them from your phone and share them with a doctor anywhere in the world.

Why choose an accredited lab — not a middleman

You will find apps and platforms that market "lab tests for expats" and send a nurse to your hotel. Many of them do not run a laboratory at all: they take a margin and route your sample to an unnamed partner lab. That is fine for convenience, but you lose transparency about who actually analyses your blood.

Laboratorio Aclimu is the laboratory itself. We are:

• Accredited by ITAES (the Argentine institute that accredits healthcare establishments), with internal and external quality controls.
• Over 30 years in operation, with matriculated biochemists on site.
• Transparent: your sample is processed in our own lab, and your report carries a named technical director — not an anonymous "partner".

Where we are and how to book

Laboratorio Aclimu is at Marcelo T. de Alvear 2337, in Recoleta (Barrio Norte) — a central, walkable part of Buenos Aires, a few steps from Subte line D (Pueyrredón station) and the Hospital de Clínicas.

Booking takes about two minutes:

1. Choose your tests and reserve a time online.
2. Come in at your slot — sample collection takes only a few minutes.
3. Receive your results in the online portal, ready to download or email.

If you are not sure which test you need, our team can point you in the right direction in English before you book.

A quick checklist for travelers and expats

• Bring your passport — it is all you need to identify yourself as a private patient.
• Check fasting requirements — glucose and lipid panels usually need 8–12 hours of fasting; most other tests do not.
• Book online to pick a convenient time and avoid waiting.
• Keep your results — the PDF report works with any doctor, in any country.

Whether you are passing through, working remotely for a few months, or settling in, you can take care of your health in Buenos Aires without the wait times and costs you may be used to — at a real, accredited laboratory.

Frequently asked questions

Do I need a doctor's order to get a blood test in Buenos Aires?

Not for many of them. STI panels (HIV, syphilis, hepatitis B and C), pregnancy blood tests, thyroid profiles and most routine check-ups can be booked and paid for privately, with no prescription. Tests billed through insurance do require an order and prior authorisation.

How fast are the results?

Routine blood work (CBC, glucose, lipid profile, liver and kidney panels) is usually ready in 24 to 48 business hours, published to a secure online portal you can open from your phone. Molecular PCR tests take 48 to 72 hours, and specialised genetic studies have their own timelines.

Can tourists and foreigners get tested? Do I need insurance or a local ID?

Yes. You can be seen as a private (particular) patient — no local insurance, no residency and no DNI are needed, just a passport for identification. You pay a published price and receive your results online, which you can share with a doctor anywhere.

Where is Laboratorio Aclimu and how do I get there?
