Creatinine is a waste product from muscle metabolism. Measuring creatinine levels helps assess how well your kidneys are filtering blood.
eGFR estimates your kidneys’ filtering capacity. Lower eGFR values may indicate reduced kidney function or chronic kidney disease.
The Creatinine & eGFR home blood test is an at-home blood test designed to assess kidney function. Creatinine is a waste product filtered by your kidneys, and the estimated glomerular filtration rate (eGFR) calculates how efficiently your kidneys remove waste from the blood.
This blood test kit is ideal for individuals who:
Follow these steps for accurate results:
Fasting is not usually required for a creatinine and eGFR home blood test. However, avoid heavy exercise and stay hydrated before sampling to help ensure accurate readings.
Our home blood testing kit uses the TDL Tiny self-collection system, validated to provide accurate creatinine and eGFR measurements comparable to clinic-drawn samples. Follow the included instructions carefully for best results.
Collect your small-volume blood sample using the lancet and TDL Tiny kit provided. Apply drops of capillary blood to the collection card, seal per instructions, and return via the prepaid mailer. Detailed steps are in the kit guide.
Your eGFR (estimated glomerular filtration rate) reflects how well your kidneys filter waste. A normal eGFR is usually above 90 mL/min/1.73 m². Lower values may suggest reduced kidney function and should be reviewed by a healthcare professional.
Once our lab receives your TDL Tiny sample, results are typically available within 2–3 working days. We’ll notify you by email or SMS when you can view your secure online report.
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.
