Full general blood and urine check-up
- First line
Full general blood and urine check-up with full blood count, glucose, cholesterol, kidney and liver function, sodium, potassium, ferritin, TSH and urinalysis with sediment. It extends the basic check-up to assess iron stores, the balance of salts and abnormalities that only appear in urine.
No prescription or appointment needed
Results in 1-2 working days
Blood and urine sample. Includes: Full blood count · Glucose · Lipid profile and ratios · Urea · Creatinine and eGFR · Uric acid · Sodium and potassium · AST, ALT and GGT. 12 in total. See what each one measures
What it is for
It serves as a broader general check-up than the basic blood test. Ferritin can show low iron stores even when the full blood count is still normal, and urine can show findings that do not appear in a blood sample.
It is designed for people who want to combine blood and urine in the same check-up, or who want to include iron and electrolytes. It does not replace targeted tests if there are specific symptoms, and a normal result is not a complete guarantee of health.
When it is recommended
- A general check-up that includes both blood and urine
- Tiredness, heavy periods or suspected low iron stores
- A personal or family history of kidney or urinary disease
- Treatments or conditions that can change sodium or potassium
- Several years without a general blood test
Clinical comment
The most useful clinical difference from the basic profile lies in ferritin and urine. Iron deficiency can appear before anaemia, so a normal full blood count does not always exclude low stores. Nor should ferritin be read on its own: it can rise with inflammation, infection or liver disease.
Urinalysis can show blood or protein, but an isolated finding does not mean kidney disease. Intense exercise, menstruation, fever and a contaminated collection can all affect the sample, and it often has to be repeated under good conditions.
As in the basic blood test, we have included TSH on clinical judgement, not because there is a universal screening recommendation. We have also avoided adding tests that are only useful for a specific indication. The aim is to extend the information that may be relevant without turning the profile into an indiscriminate list.

What is tested
- Full blood count
- Checks red blood cells, white blood cells and platelets, and can show anaemia and other blood cell abnormalities.
- Glucose
- Measures fasting blood sugar.
- Lipid profile (total cholesterol, HDL, LDL, triglycerides) and ratios
- Urea
- Adds complementary information about hydration, protein metabolism and kidney function.
- Creatinine and eGFR
- Assess kidney function.
- Uric acid
- Can show hyperuricaemia.
- Sodium and potassium
- Assess the balance of electrolytes, which can change with illness, digestive losses or certain medicines.
- AST, ALT and GGT
- Enzymes that point to possible liver abnormalities.
- Total bilirubin
- Completes the assessment of the liver and of the breakdown of red blood cells.
- Ferritin
- Estimates iron stores and can show iron deficiency before anaemia appears, although it also rises with inflammation.
- Urinalysis and sediment
- Looks for protein, blood, glucose, white blood cells and other urine abnormalities.
- TSH
- The first test for assessing thyroid function.
How to prepare
Fast for 8 to 12 hours. You can drink water. Bring a sample of your first urine of the morning or collect it at the partner centre. Avoid alcohol and intense exercise the day before. If you are menstruating or have symptoms of a urinary infection, say so, because it may be better to postpone the urine sample.
You can add
Without another needle. It is offered when you order, so you do not have to decide now.

Recomendaciones preventivas cardiovasculares. Actualización PAPPS 2024
Acknowledges that there is no evidence to set an age or an interval for cholesterol screening, and chooses to include it in any blood test ordered from the age of 18, with a minimum interval of four years. It supports the lipid profile in this test, not the panel as a whole.
American Diabetes Association · Standards of Care in Diabetes 2026 · Diabetes Care 49(Supl 1):S27-S49
Diagnosis and Classification of Diabetes
Recommends screening for diabetes from the age of 35 with fasting glucose or glycated haemoglobin. Neither the urinalysis with sediment nor ferritin comes from a screening recommendation for healthy people: they are included on clinical judgement, because ferritin explains tiredness that the full blood count does not pick up, and urine can reveal silent kidney problems earlier.
