Q.

Why Are RapID Tags® Better Than Traditional, Manual ID Methods Like Ear-Notches/Punches, Tattoos, And Toe-Clipping?

A.

Manual animal identification methods can be easily misapplied and are often misread, with sometimes serious consequences. Ear-notches/punches can grow back making accurate identification increasingly difficult or impossible. They can also require punching from one to eight holes. All traditional, manual lab animal ID methods are painful to the rodent and potentially a source of infection. Tattoos are associated with an immune response (macrophage infiltration) which is usually undesirable for some research. RapID Tags are the most humane, accurate, multi-color, automated, lab animal ID tags available.

Q.

How Do RapID Tags Compare To Metal Ear-Tags?

A.

  • They weigh a fraction of metal ear-tags so there is no deformation of the ear shape which could impact hearing. Animals typically do not notice RapID Tags applied to their ears.
  • They are easier to apply than metal ear-tags and require only nominal training.
  • They are quickly scanned with popular lab scanners, unlike metal ear-tags.
  • RapID Tags automatically collect data, unlike metal ear-tags.
  • They are multi-colored for fast, visual (secondary) identification, unlike metal ear-tags.
  • They are made from an advanced, medical-grade, polymer that is highly chew-resistant and much less prone to dislodge than metal ear-tags.
  • RapID Tags are 100% autoclavable and MRI compatible, unlike metal ear-tags.

Q.

Do RapID Tags Cause Tissue Reactions Like Metal Ear-Tags?

A.

RapID Tags are manufactured from biologically inert, medical-grade polymers which virtually eliminate tissue reactions. Histological and macroscopic examinations of ears have shown no evidence of tissue inflammation, only tissue healing around the small hole for the single post used in the RapID Tag design.

Q.

Can RapID Tags Get Torn Out Of The Ear Like Metal Ear-Tags?

A.

While any ear-tag has the potential to be torn out, unlike standard metal ear-tags, RapID Tags are much less irritating and thus less likely to cause scratching. They also have no loop structure to easily get caught in an animal’s phalanges

Q.

Can RapID Tags Get Chewed Off By Other Cage Animals?

A.

RapID tags are made of an extremely hard polymer plastic securing a specially-hardened metal barcode plate. These features make it very unlikely that RapID Tags can become destroyed by an aggressive cage-mate

Q.

Do RapID Tags Require A Laser Scanner?

A.

No. RapID Tag’s 2-D matrix barcode is easily and quickly scanned (normally about 1 second) by the Code CR1400 model light scanner or other popular ordinary-light scanners.

Q.

Can RapID Tags Be Removed?

A.

Yes. Using the RapID Tag Removal Tool makes it an easy and quick process to remove a RapID Tag previously applied to a rodent’s ear. The mouse ear tag removal process is painless to the rodent, and won’t damage the ear, while maintaining the integrity of the barcode.

Q.

What Is The Difference Between A Barcode And RFID?

A.

Barcodes are visible codes of lines or squares like those seen on products purchased at supermarket. Barcodes are scanned by ordinary light scanners or laser scanners using an appropriate scanning device. Unlike most product barcodes made of lines, RapID Tags have a 2-D matrix barcode which is square in shape and very tiny in size (less than 5mm X 5mm). Each barcode represents one of millions of unique animal identification numbers.

RFID is a passive electromagnetic microchip chip encased in glass then surgically inserted into the rodent. When the animal (and chip) are exposed to electromagnetic radiation, the chip is energized and transmits an electromagnetic signal that is interpreted by the RFID receiver and converted into an animal identification. Microchips have been associated with spontaneous tumor developments.

Q.

How Do RapID Tags Compare With RFID Chips?

A.

  • They do not require anesthesia or specialized training, unlike RFID chips.
  • They are more humane and less invasive than RFID chips.
  • They are quick and easy to apply, unlike RFID chips.
  • RapID Tags are multi-colored for fast, secondary (visual) identification, unlike RFID chips.
  • They are visible, unlike RFID chips.
  • They are 100% MRI compatible, unlike RFID chips.
  • They are a much better value, costing a fraction of RFID chips. Additionally, RapID Tags use ubiquitous laboratory light scanners instead of costly, custom, RF transmitters and receivers.

Q.

Why Should I Care About Animal Identification Errors Enough To Switch To RapID Tags?

A.

Animal identification errors associated with manual ID methods may cause expensive errors in studies. These errors include administering the wrong treatments to animals or collecting wrong measurements, which cost time, money and impact data integrity. Every time an animal identification error occurs, the integrity of the study is compromised, sometimes completely. When considered cumulatively, the cost of ID errors far exceeds the nominal cost of the RapID Tags used for each study.

Using RapID Tags, the identification is automated so scanning the tag hands-free is significantly faster than manual methods. And because no interpretation is required, and when used in conjunction with study management or facility software, data collection time is also optimized. Time and labor savings identifying animals adds up quickly over the course of each study with regular measurements. When all things are considered together, i.e., the cost of the animals, the labor, and the entire study costs, the unequivocal accurate identification of each animal using RapID Tags is easily justified.

Q.

At What Age Can I Apply A RapID Tag To A Mouse Pup?

A.

RapID Tags have been applied to lab mice at three weeks without any problems. It may be possible to apply them to younger mice, but we cannot guarantee their use until ongoing testing has been completed.

Q.

Have RapID Tags Been Industry Tested?

A.

Yes. RapID Tags have undergone both histology testing and actual in-laboratory testing at numerous organizations. Results from these studies have confirmed that RapID Tags perform very well with no inflammation issues noted to date. RapID Lab maintains an ongoing development program which benefits from customer feedback and suggestions used in continued improvement of the product.

Q.

Will RapID Tags Work With My Scanner, Computer And Software?

A.

Scanning RapID Tags with popular laboratory scanners, like the CODE CR1400 scanner, works well with many configurations of software and hardware. More detailed information about software and hardware configurations can be found HERE.
