FAQ for Implanters

What protocol are petDetect Trovan microchips?
The Trovan microchips we supply conform to the FDX-B protocols set out in ISO 11784/11785. ISO compliant microchips are programmed with a number that is 15-digits long. The first three numbers denote the manufacturer – our Trovan number is 956. There are then a series of noughts and then 6, 7 or 8 digits. Trovan microchips are ‘read-only’ and are laser programmed so they cannot be re-programmed.

Do other microchip protocols/technologies exist?
Yes there are other microchip technologies that exist - the most common one being FDX-A microchips which are programmed with a number that is 10-digits long. Although most of the world now use ISO compliant microchips, some older pets, especially exotics, or pets imported from the USA may have FDX-A microchips implanted. Many microchip scanners may read FDX-A as well as the FDX-B microchips, however they are generally only capable of reading the Destron/FECAVA FDX-A microchips. Some manufacturers also produce encrypted microchips which cannot be read by many scanners - these may again be implanted in pets from the USA. Notable examples of microchips which require a brand specific, or universal scanner to be read include the Trovan Unique and AVID Encrypted (Friendchip).

Are your microchips guaranteed?
Yes, of course. In fact, all of our equipment is guaranteed against manufacturing faults. Most of what we sell is made in the UK or in Europe.

Why should I use petDetect Trovan microchips?
There are now lots of different manufacturers and suppliers of microchips in the UK. However, it is important to note that although they must all comply with the ISO standards, this is not a mark of build or material quality, or even code uniqueness. These remain the responsibility of the manufacturer, and therefore the quality and reliability of the microchips available to implanters can vary greatly.

Trovan have been manufacturing microchips since the 1980s and hold a number of patents for their technologies. Trovan microchips are used worldwide in zoos and wildlife projects due to their proven reliability, especially important when used in long-lived species.

Do you sell the 8mm mini microchip?

Yes. Implanters can choose to use either the regular 12mm microchip or mini 8mm microchip. Using either one, you can have confidence that any scanner capable of reading FDX-B microchips can read them.
If you are not sure what size to use, see our guidance on What size microchip should I use?

Scanning techniques are important when attempting to read a microchip - see our guidance on How to scan for a microchip. Remember to hold the reading ‘hot-spot’ on the scanner so that it touches the fur and scan SLOWLY.

What is the ‘backtrack’ system?
When microchips are sold to an implanter, we keep details of when and where every microchip we sell has been sent. This information is also sent to Petlog which means that, if necessary, pets can even be traced before Petlog receives registration details or in cases where registration wasn’t successfully carried out. In a case where a registration has not been processed, Petlog will be able to retrieve information on the implanter the microchip was allocated to. Keeper details can then be obtained via the records that each implanter must keep for each microchip they insert.

Do I need to keep records of all implantations that I carry out?
Yes, this is extremely important. The backtrack system is in place to ensure that if required we can identify when, where and what microchip was implanted into an individual animal, as well as what keeper and animal details were originally registered alongside that microchip on the Petlog database. This information may be required for example in cases where registration wasn’t completed successfully, or incorrect contact details were registered and are needed to help reunite an animal with it’s owner.

Can anyone buy your microchips?
As a member of the Microchip Trade Association, we abide by a code of conduct to only supply microchipping equipment to implanters whom we can verify have been appropriately trained - including meeting the training requirements outlined in any relevant legislation. If we cannot verify this training, then you will not be permitted to purchase microchips from us. We promote the responsible supply of microchips to trained persons only.

We use another brand of microchips - can we use the 'petDetect' Petlog paper registration forms?

No. Please contact the supplier of your microchips.

What happens if I misfire a microchip?
We understand how frustrating misfires can be. If implanters misfire a microchip they need to look at their technique, whether the animal was restrained effectively and also check their implant equipment. A misfire on a very rare occasion is understandable, however if implanters are misfiring regularly then do give us a call and we can advise you accordingly about remedying this. 

Alternatively misfires also occur because the trigger/plunger of the implanter was depressed too early, too late, or the Implanter failed to depress the trigger fully. With some implanters using the gun style tool we see them wrapping fingers around the 'trigger' on the implant gun as they push, if they encounter resistance or movement then this often results in them squeezing the trigger and misfiring. If this is happening, then we recommend switching to the syringe type implanter or the all-in-one format microchips - most vets prefer these.

My sharps box is full - how do I dispose of it legally?
By law a sharps box must be incinerated. You are unable to do this, so please make enquiries with your local council to ask if they offer a sharps drop-off or pick-up service. Alternatively, you can ask any company or clinic that are dealing with needles if they can take yours for disposal. They may ask for a small fee to do this. You can buy a replacement sharps box from a chemist or alternatively we can supply them to you.

A microchip that I implanted is now not scanning - what do I do?
True mechanical failure of microchips is very rare, many cases of microchips failing to scan are due to scanner errors or incorrect scanning technique. Other possible causes are that the microchip wasn’t successfully implanted in the first instance, or the microchip migrated and was expulsed from the body soon after implantation.
Firstly, ensure that the animal is scanned thoroughly, with two different scanners preferably. For more information on proper scanning technique please click here. If a microchip is still not found and the implantation has only just taken place, scan the floor and table where the implantation took place, and the microchip needle, as the microchip may be found there.
If not found then please contact us on 01962 813 554 for further advice before inserting another microchip. The only way to distinguish whether a microchip has failed or has been expelled from the body is to radiograph or ultrasound the implant area.
Remember that adverse events relating to microchips implanted in dogs in England, Wales and Scotland must now be reported to the VMD, see our FAQs- Adverse Events page for more information.
