The Hidden Problem in Every Blood Test
“Every day, millions of blood samples are collected across India. But here's the hidden problem the blood often starts changing even before it reaches the lab. Those changes silently distort diagnostic results.”

Together, we are developing next-generation vacutainers using oxalate-based nanoparticles that preserve blood more accurately, for longer.
From Diagnostic Errors to Diagnostic Excellence
EDTA has been the diagnostic default for decades yet it silently distorts millions of results every day. OxaStore solves this at the chemistry level.
The Problem
EDTA The Outdated Standard
Cell Stability
Deforms within 9 hours
Echinocytes distort CBC results
Glucose Level
111 → 52 mg/dL collapse
Glycolysis destroys metabolic data
Sample Window
Only 2–4 hours viable
Missed samples in remote transport
Tubes Needed
Multiple tubes per patient
EDTA + citrate + serum separately
Cost Per Vial
₹32–120 per tube
Imported, expensive, inflexible
Platelet Count
False low readings (PTCP)
Artificial clumping fakes results
The Solution
OxaStore NPs Engineered to Excel
Cell Stability
Stable for 24+ hours
No morphological changes in RBCs
Glucose Level
106 → 98 mg/dL (stable)
Glycolysis halted precise panels
Sample Window
Extended to 48 hours
More time, more reliable results
Tubes Needed
One tube for all assays
CBC, coagulation, glucose & more
Cost Per Vial
₹20–22 per tube only
Made in India 80% cheaper
