Cardiovascular
- Advanced lipid testing (ApoB & Lp(a))Beyond the standard lipid panel: what ApoB and Lp(a) add, when European guidelines suggest measuring them and how to prepare.
- Electrocardiogram (ECG)An ECG records the heart's electrical activity. What a clinical ECG shows, how it differs from a smartwatch ECG, and when it is used.
- Lipid panel (cholesterol test)A lipid panel measures total cholesterol, LDL, HDL and triglycerides. Learn what the test includes, how to prepare and which extra markers to discuss.
Kidney
- Kidney function testsKidney function tests use creatinine, eGFR and urine albumin to assess how well your kidneys filter. Learn what's included and who should be tested.
- UrinalysisA urinalysis checks the appearance, chemistry and microscopic content of urine. What it can reveal about the kidneys, urinary tract and metabolism.
- Urine albumin-to-creatinine ratio (UACR)The urine albumin-to-creatinine ratio detects small amounts of albumin in urine — an early sign of kidney damage. Who should have it and how it is interpreted.
Metabolic
- Metabolic panel (BMP / CMP)A metabolic panel checks glucose, kidney function, electrolytes and — in the comprehensive version — liver markers. Learn what's included and how to prepare.
- Oral glucose tolerance test (OGTT)An oral glucose tolerance test measures how the body handles a sugar drink over two hours. When it is used to diagnose prediabetes and diabetes and how to prepare.
