No
The description explicitly states that the Unistik® Pro is a single-use safety lancet used to obtain a capillary blood sample, not to perform a diagnosis itself. It is used as part of the process for in-vitro diagnostic assays, but it does not analyze or interpret the sample.
No
The device description clearly states it is a "sterile single-use safety lancet, a hand-held disposable device" with different needle gauges and penetration depths, indicating it is a physical hardware device.
Based on the provided text, the Unistik Pro is an IVD (In Vitro Diagnostic) device accessory.
Here's why:
- Explicitly Stated in Device Description: The text clearly states: "The Unistik® Pro sterile single-use safety lancets are indicated for use where a capillary blood specimen is required for the purposes of performing in-vitro diagnostic (IVD) assays..."
- Intended Use Supports IVD: The intended use is to obtain a capillary blood sample, which is a necessary step for many IVD tests (like blood glucose monitoring).
- Mention of IVD Self-Testing: The text mentions the device is designed for "lay (home) users to be able to perform a skin puncture on themselves where an IVD self-testing regime is required."
While the lancet itself doesn't perform the diagnostic test, it is an essential component used to obtain the sample required for the IVD assay. Therefore, it functions as an accessory to the IVD process.

Device Description
The Unistik® Pro is a sterile single-use safety lancet, a hand-held disposable device intended to be used to achieve a controlled skin puncture on the fingertip, in order to obtain a capillary blood specimen. The Unistik® Pro sterile single-use safety lancets are indicated for use where a capillary blood specimen is required for the purposes of performing in-vitro diagnostic (IVD) assays, e.q., for blood glucose monitoring in patients with diabetes,
The Unistik® Pro safety lancets are available in 3 different variants, each with a different needle gauge (21G, 25G and 28G with penetration depths of 2.0mm, 1.6mm and 1.2mm respectively) as required by the patient.
The Unistik® Pro sterile single-use safety lancets are designed for prescription and over-thecounter use and to be used by self-testing patients, care-givers and healthcare professionals. The devices are designed to perform a controlled skin puncture on the finqertip, in order for caregivers and healthcare professionals to obtain capillary blood specimens from patients for IVD assays, and also for lay (home) users to be able to perform a skin puncture on themselves where an IVD self-testing regime is required. The intended user population includes male and female, right or left-handed self-administering patients, care givers and healthcare professionals. The frequency of use and intended patient population is dependent on the given diagnostic regime.
The Unistik® Pro sterile single-use safety lancets feature integral sharps protection whereby the lancet needle is shielded before and after use to prevent needlestick injuries, so mitigating the hazard of transmission of blood-borne infectious agents. Furthermore, the device automatically self-disables after a single use, thus preventing any hazards of re-use.
