Why get tested
One sample reads across seven systems at once — the difference between guessing how you feel and knowing where you stand.
Cholesterol balance and cardiovascular markers.
Filtration and waste-clearance signals.
Enzymes and proteins that flag strain.
Stores and transport behind your energy.
Average glucose and metabolic control.
The hormone that paces your metabolism.
Vitamin D, B12, folate and minerals.
"Not a substitute for medical advice — a head start on the conversation."
Start with one testThe collection device
The part most people dread is the part we redesigned. Tasso+ sits on your upper arm and draws a sample gently, so the only clinical thing about test day is the data.
A press-on device that opens micro-channels — no needle, no finger prick.
Collect at the kitchen table whenever it suits you, morning or evening.
The volume and stability Randox needs for accredited analysis.
What gets tested
Every result arrives sorted into the health area it speaks to — so a number always comes with its meaning.
