Kidney Test - Lab in the Box

Kidney Test – Complete Assessment of Kidney Function at Home

THE Lab in the Box Kidney Test analyzes the 3 essential markers to monitor your kidney health: urea, creatinine, and GFR (Glomerular Filtration Rate) . Ideal for early detection of changes in kidney function, especially important for diabetics, hypertensive patients, or those with a family history of kidney disease.

With a simple at-home blood draw, get accurate results in 24-48 hours and proactively manage your kidney health.

🔹 Painless collection (finger prick)
🔹 Results in 24h-48h by email
🔹 Complete kit with free shipping
🔹 Medical monitoring available

Evaluated Parameters:

• Urea – Product of protein metabolism; high levels may indicate kidney problems or dehydration.
• Creatinine – Residue of muscle activity; sensitive marker of kidney function.
• TFG – Measures how efficiently the kidneys filter blood (the most accurate indicator of kidney health).

Includes in the Kit:

✔️ All collection material (yellow cap tube)
✔️ Detailed instructions + explanatory videos
✔️ Prepaid shipping envelope
✔️ Digital results with reference values

Collection Recommendations:

• Mandatory fasting (8-12 hours)
• Perform before 11:30 am (Mon. to Thu.)
• Ship same day
• Blood volume: 400 μL

Reference Values:

• Urea : <50 mg/dL
• Creatinine : <1.11 mg/dL
• GFR : > 60 mL/min/1.73 m²

Suitable for:

• Diabetics or hypertensive (risk groups for kidney disease)
• People with family history of renal failure
• Who uses nephrotoxic drugs (e.g., anti-inflammatories)
• Athletes who consume protein supplements in excess
• Who presents symptoms as:
  • Swelling in the legs or face
  • Changes in urine (foam, dark color)
  • Unexplained fatigue

Why Monitor Kidney Health?

• Kidney diseases are silent in the early stages.
• GFR below 60 may indicate moderate renal failure.
• High creatinine + high urea suggest renal overload.

Practical Example:
A result with GFR = 50 mL/min requires medical evaluation, even without symptoms.

THE Kidney Test is essential for those looking for prevention or already have risk factors, allowing early interventions to preserve kidney function.
