Medical laboratories in Saint-Louis: a practical guide
Need a blood test or lab work in Saint-Louis? The city has several private laboratories and health facilities that handle routine tests, from a full blood count to prenatal screening. This guide explains how to prepare: prescriptions, fasting, typical turnaround times and how to pick a lab. To compare options, browse our directory of laboratories and health services in Saint-Louis.
Before you go: prescription and paperwork
Most labs will ask for a prescription written by a doctor, midwife or other healthcare professional. It lists the tests you need and avoids any confusion at the counter.
Bring along:
- your original prescription, plus a photo of it on your phone;
- an ID document;
- your IPM, mutual insurance or health insurance card, along with any coverage approval;
Prices depend on the tests and on the lab. Always ask for a quote at the desk before the sample is taken, especially for full check-ups. It is the simplest way to avoid surprises.
Fasting: what you need to know
Some tests, such as blood sugar or a cholesterol panel, require you to be fasting, which usually means nothing to eat since the evening before. Plain water is generally fine, but skip coffee, sweet tea, ataya and cigarettes. Your doctor or the lab will confirm the exact instructions.
Practical tips:
- go early in the morning, when fasting samples are usually taken, so you can eat soon afterwards;
- if you take regular medication, never stop it on your own: ask your doctor;
- during Ramadan, tell the lab you are fasting so they can suggest a suitable time.
In the hot season, roughly May to October, drink enough water the day before: being well hydrated makes the blood draw easier.
Turnaround times and collecting results
Timing depends on the test. Routine work (blood count, blood sugar, blood group, pregnancy test) is usually ready the same day or the next day. Hormone panels, serology or cultures can take several days, and some specialised tests are sent to other labs, sometimes in Dakar, which adds time.
When your sample is taken, ask:
- when the results will be ready;
- whether they can be sent by email or message, or must be collected in person;
Lab results should never be read in isolation: consult a healthcare professional to interpret them. This article is for information only and is not medical advice.
Family planning and women's health
Saint-Louis has organisations focused on reproductive health: contraception, pregnancy follow-up and screening. Family planning centres can point you to the tests you need, confidentially.
Neighbourhood health posts and health centres, in Sor, Pikine, Guet Ndar or Balacoss, are also a good first stop for guidance.
Choosing a lab in Saint-Louis
The city stretches from the Island to the mainland district of Sor, through Guet Ndar, Diamaguène, Pikine and Sanar. A few simple criteria:
- distance: crossing the Faidherbe bridge at rush hour takes time, so if you are fasting, choose a lab close to home;
- coverage: check that your IPM or insurer is accepted;
- tests available: ask whether your test is run on site or sent elsewhere;
- how results are delivered, which matters for diaspora members managing a parent's care from abroad.
In an emergency, do not wait for a lab: call SAMU on 1515 or the fire and rescue service on 18.
