Our Guarantee: Zero X-Ray Exposure
Every GuardianCryo shipment includes documented proof that your specimens were hand-inspected at all security checkpoints. We provide a complete chain-of-custody log with your delivery confirming NO ionizing radiation exposure throughout the entire journey.
X-Ray Screening vs. Hand Inspection
Standard X-Ray Screening
- Specimens pass through ionizing radiation
- CT scanners use higher radiation doses
- Multiple exposures at connections
- Unknown cumulative effects on DNA
- No documentation provided
GuardianCryo Hand Inspection
- Zero radiation exposure guaranteed
- Visual inspection only (exterior)
- Dewar never opened at checkpoints
- TSA-approved medical protocol
- Full documentation provided
Our 5-Step Hand Inspection Protocol
How our couriers ensure your specimens bypass X-ray at every checkpoint
Pre-Flight Documentation
Our courier carries official TSA/ICAO medical transport declaration letters, IATA DGR certification, and clinic documentation identifying the biological nature of the shipment.
Security Checkpoint Approach
At TSA screening, our courier immediately identifies themselves as carrying temperature-sensitive medical specimens and requests manual inspection per TSA guidelines.
Hand Inspection Process
TSA agents perform visual inspection of the exterior dewar. Explosive trace detection (ETD) swabs may be used on the outer container. The dewar is NEVER opened.
Documentation Verification
TSA reviews our official documentation. Our couriers are trained to calmly explain the medical necessity and provide any required information.
Cleared for Travel
Once cleared, the courier proceeds to the gate with specimens in hand. The dewar travels in the cabin, never in cargo or through any screening equipment.
Why We Take a Zero-Risk Approach
Precautionary Principle
Even without definitive evidence of X-ray damage, we believe irreplaceable specimens deserve zero-risk handling. Why take chances with your future family?
Industry Best Practice
Leading fertility clinics and embryologists recommend hand inspection for cryogenic specimens. We follow the highest standards of care.
Full Documentation
Every shipment includes a complete chain-of-custody log confirming no X-ray exposure at any checkpoint throughout the journey.
Frequently Asked Questions
Do frozen embryos go through X-ray machines at airports?
Not with GuardianCryo. Our couriers carry official TSA declaration letters and request manual hand inspection at every security checkpoint. Your embryos never enter X-ray tunnels or CT scanners.
Can X-rays damage frozen embryos?
While there is no definitive scientific evidence that airport X-rays damage frozen embryos at cryogenic temperatures, the precautionary principle applies. GuardianCryo takes a zero-risk approach—we never expose specimens to any ionizing radiation.
Does TSA allow hand inspection for medical specimens?
Yes. TSA guidelines permit alternative screening methods for medically necessary items. Our couriers are trained in proper request procedures and carry all required documentation to facilitate smooth hand inspections at US airports.
