Creatinine is a by-product of muscle metabolism. High creatinine suggests impaired kidney function, as healthy kidneys remove it efficiently.
Estimated Glomerular Filtration Rate calculates kidney filtering capacity based on creatinine, age and sex. A key marker of overall kidney health.
Urea is a waste product formed from protein breakdown. Elevated levels can indicate reduced kidney filtration or dehydration.
This home blood testing kit measures three key markers of kidney health: urea, creatinine and estimated Glomerular Filtration Rate (eGFR). Monitoring these levels helps detect impaired kidney function early.
Use the lancet provided to prick your finger, collect a few drops of blood on the card and allow it to air dry. Then, place it in the protective sleeve and return it using the pre-paid envelope.
This at-home blood test is designed for ease and accuracy. You’ll receive secure online results within 3–5 working days after receipt at the lab.
Yes. Our home kidney function blood test kit allows you to measure urea, creatinine and eGFR from the comfort of your home. Simply follow the step-by-step instructions, post your sample to our accredited lab, and receive results online within days.
Our TDL Tiny self-collect kit is designed for small-volume blood sampling and has been validated for accuracy. When you follow the instructions correctly, results for urea, creatinine and eGFR are comparable to those from a clinic.
To test your creatinine levels at home, use the self-collect lancet included in your kit to obtain a few drops of blood. Place them on the collection card, seal and post back. You’ll receive your creatinine result along with urea and eGFR.
eGFR is calculated from your creatinine result plus factors like age and sex. When you return your sample, the lab will generate your eGFR so you don’t need any calculations yourself.
If you have high blood pressure, diabetes, a family history of kidney disease or are over 60, regular kidney function checks can help detect early changes. Always talk to a healthcare professional if you’re concerned.
Get started by choosing the right at-home blood test kit for your needs — whether it's for cholesterol, thyroid, vitamin levels, or general health screening. Your kit is delivered in discreet, secure packaging.
Using our easy-to-follow instructions, collect a small blood sample with the included lancet and tube. No need for a clinic visit — everything you need for accurate testing is in the kit.
Place your sample in the prepaid return envelope and post it to our certified partner lab. Our labs follow the highest standards to ensure fast, reliable blood analysis.
You’ll receive a text message with your results as soon as they’re ready — usually within 1–3 days. A full lab report is included, giving you a clear breakdown of your blood test findings. Need help understanding your results? You can book a follow-up consultation with one of our clinicians at any time.
