The GetTested At-Home Kidney Function Test is a dried blood spot (DBS) test designed to evaluate essential markers of renal health. It primarily measures Creatinine, Blood Urea Nitrogen (BUN), and calculates your estimated Glomerular Filtration Rate (eGFR), providing a comprehensive snapshot of how effectively your kidneys are filtering waste products. This method offers a convenient and reliable alternative to traditional venipuncture by analyzing a small blood sample collected at home, then processed in our CLIA-certified laboratory.

This test is ideal for individuals monitoring their kidney health, especially those with increased risk factors for kidney disease such as diabetes, high blood pressure, a family history of kidney issues, or those taking medications that may impact renal function. It’s also beneficial for anyone seeking proactive insights into their overall organ health and functional wellness. Regular testing allows for early detection of potential changes, emphasizing preventive care even without a doctor's immediate order.

The sample collection involves a simple finger-prick to obtain a few drops of blood onto a specialized collection card. Detailed instructions, including troubleshooting tips for successful collection, are provided in your kit. We recommend collecting your blood sample in the morning after an overnight fast (no food or drink except water). DBS collection ensures a less invasive and convenient experience compared to traditional clinical draws.

Your comprehensive results are typically available within 2-5 business days from the time our lab receives your sample. The price includes the complete at-home collection kit, laboratory analysis of your dried blood spot sample for Creatinine, BUN, and eGFR, and a secure, easy-to-understand digital report. All necessary shipping for returning your sample is also covered, ensuring a seamless and transparent process with no hidden fees.

Our GetTested At-Home Kidney Function Test processes samples in CLIA-certified laboratories, adhering to rigorous quality control standards to ensure high accuracy and reliability. While dried blood spot (DBS) testing is a validated method, nuances exist; variations could theoretically arise from improper collection or certain physiological states. Many independent studies support the concordance of DBS testing with traditional venipuncture for these specific kidney markers, providing trusted data for monitoring renal health parameters effectively. Our expert team continuously reviews methods to uphold the highest analytical standards.

Your detailed report will clearly present your Creatinine, BUN, and eGFR values alongside established 'normal' reference ranges. While these ranges provide a general guide, individual variation exists and is influenced by factors like age, sex, and muscle mass. If any marker falls outside the expected range, it may indicate a need for further medical evaluation. Our reports are designed for clarity, but they do not replace professional medical advice; we guide you on discussing any anomalous findings with a healthcare provider for personalized interpretation and next steps.
