Implantation Guidelines

idENTICHIP® is available in two types of implanter...

identichip implanters

Implantation Handle

The implanter is a plastic, pistol grip handle in which the needle is located.

The idENTICHIP® comes in its own sterile needle assembly. The slide on the top of the implanter is drawn back to allow this assembly to be located in the handle and the slide pushed back over the needle to secure. At the time of insertion the idENTICHIP® is ejected from the needle by pushing the thumb button forward in one continuous movement.

The implanter handle is not supplied sterile as the design ensures that no part of it comes in contact with the patient during insertion. It is however suitable for cold liquid sterilisation between patients if desired.


The idENTICHIP® comes in a preloaded single use, 2.5ml syringe style implanter.


Implantation Procedure

Before insertion always check that the idENTICHIP® can be read whilst still in its package and that the microchip number when scanned matches the printed barcode label.

Use the bar code labels on Registration Forms and Patient Record Cards to avoid any possible errors in copying numbers.

Appropriate measures of restraint are recommended for all species.

The site of implantation requires little preparation and we would recommend use of your normal pre-injection routine. Local anaesthesia can be used if felt necessary and the procedure can be performed under general anaesthetic if other procedures are being performed.

It is important to use a 3-stage injection technique.

  • Insert needle to full depth
  • Expel idENTICHIP® to full extent from needle
  • Withdraw needle

This will ensure that the idENTICHIP® is deposited at its full depth at the end of the needle tract and will minimise the risk of immediate ejection.

It will aid subsequent reading of the idENTICHIP® if all implanters for each species use a preferred site.

The following sites are strongly recommended.


Species Guidelines…

Small Companion Animals

The preferred site is subcutaneously midline in the scruff of the neck in front of the shoulder blades.


The preferred site is within the nuchal ligament in its middle third at the halfway point between the ears and the withers. The needle should be inserted to full depth perpendicular to the skin surface. Finger pressure should be applied to the site immediately following withdrawal of the needle.

Agricultural Animals

The preferred site for the bovine, ovine, porcine, caprine and other species used for meat production is subcutaneously at the base of the left ear on the scutiform cartilage.


>1.5kg adult weight and/or long-legged: Subcutaneously at the base of the neck.

< 1.5kg adult weight: intramuscularly in the left pectoral muscle. Direct the implanter in a caudal direction. Use tissue glue and digital pressure or a suture to seal the wound.


Up to 4 days old: in the pipping muscle behind the head on the left side.

Older birds: subcutaneously in the left thigh.


Dorsal midline in the subcutaneous lump.

Penguins and Vultures

Subcutaneously at the base of the neck.


> 30cm in length: on left side of the anterior base of the dorsal fin.

< 30cm in length: on left side into the coelomic cavity.


Left hind limb socket. Use a subcutaneous site in small chelonia and an intramuscular technique in large species as well as small species with thin skin. The wound should be sealed with tissue glue. Hibernating species should be implanted several weeks before the end of their active season in order to allow healing before hibernation.


Subcutaneously anterior to the nuchal cluster.


> 12.5 cm snout to vent length: subcutaneously in left inguinal region

< 12.5 cm snout to vent length: intracoelomic


Subcutaneously on the left side of the neck, twice the length of the head from the tip of the nose.


Into the lymphatic cavity. The wound should be sealed with tissue glue.


Subcutaneously on the left side of the tail in the main caudal fold.

Hyrax and Loris

Subcutaneously on the left side of the intralumbar area.


Subcutaneously midway on the left neck or top of the head behind the left ear.
