What is Lab Basic (General Blood Test)?
The Lab Basic package is a general blood test that measures the most essential blood values for a complete picture of your health. This package tests the three most important organ systems: kidney function, liver function, and thyroid function. In addition, important electrolytes and blood values are checked. It is a recommended test as a regular check-up to get a full overview of your health, even if you do not have specific complaints.
What is tested?
- Hemoglobin (Hb) – Oxygen-transporting protein, tests for anemia
- MCV – Mean corpuscular volume of red blood cells
- TSH (thyroid hormone) – Regulates thyroid function and metabolism
- fT4 (free thyroxine) – Active thyroid hormone
- eGFR (kidney function) – Estimated glomerular filtration rate
- Creatinine – Waste product for kidney function assessment
- ALT (liver function) – Alanine aminotransferase liver enzyme
- AST (liver function) – Aspartate aminotransferase liver enzyme
- Sodium (Na) – Electrolyte for fluid balance
- Potassium (Ka) – Electrolyte for heart and muscle function
Why should you get Lab Basic done?
This test is suitable for anyone who wants to perform a general health check. It is particularly useful for vague complaints like fatigue, when using medication that can burden organs, or as preventive screening. The test provides insight into how well your kidneys, liver, and thyroid are functioning. Abnormalities in these organs can lead to serious health problems if not detected in time. Electrolyte disturbances can also have significant consequences for the heart and muscles.
What does it indicate?
The results provide an overview of the function of your most important organs. Abnormal hemoglobin and MCV can indicate anemia or other blood disorders. TSH and fT4 show whether your thyroid is overactive (hyperthyroidism) or underactive (hypothyroidism). Creatinine and eGFR measure how well your kidneys filter waste products. ALT and AST provide insight into liver health. Sodium and potassium are crucial for fluid balance and heart function. Abnormalities often require further investigation or treatment.
What does a high level mean?
Increased hemoglobin can indicate dehydration or hemoconcentration. High TSH with low fT4 indicates hypothyroidism (underactive thyroid). Elevated creatinine means reduced kidney function. Elevated liver enzymes (ALT/AST) can indicate liver inflammation, fatty liver, alcohol use, or medication side effects. High sodium can indicate dehydration, while high potassium is dangerous for the heart and requires immediate attention. These values should always be evaluated by a physician.
What does a low level mean?
Low hemoglobin indicates anemia with associated fatigue and shortness of breath. Low MCV indicates iron-deficiency anemia. Low TSH with high fT4 means hyperthyroidism (overactive thyroid). Low electrolytes (sodium/potassium) can result from vomiting, diarrhea, or medication use and can lead to muscle weakness, cardiac arrhythmias, and confusion. Very low potassium is a medical emergency. These abnormalities usually require treatment to prevent serious complications.
Frequently asked questions
Answers to what people usually want to know.
How does it work from order to result?
After ordering we generate a referral letter and email you the instructions. You pick a collection point yourself and book an appointment there. Blood is drawn at the location, processed at the lab, and your result arrives digitally.
How quickly can I get tested?
Usually very quickly. Collection points typically have slots within a few days, sometimes even same-day. It depends on how busy the location is. For a few specialist analyses we first ship collection materials, which takes a bit longer.
Do I need to book an appointment?
At most collection points yes. Some accept walk-ins. This is clearly indicated per location. You choose the location that works best for you.
