Come riconoscere provette PRP adatte: CE, MDR, destinazione d’uso e documentazione
A prima vista, le provette PRP sembrano spesso simili: vetro o plastica, tappo colorato, confezione sterile e volume definito. Per la preparazione professionale del PRP, l’aspetto esterno non è sufficiente.
È decisivo sapere se il prodotto è adatto alla destinazione prevista, correttamente etichettato, documentato in modo tracciabile e compatibile con il relativo protocollo PRP.
Verificare la destinazione d’uso
Il punto decisivo è se la provetta è prevista e documentata per il workflow PRP professionale pianificato.
Considerare CE, MDR e IFU
Marcatura CE, istruzioni per l’uso, dati del produttore, classe del prodotto e documenti di conformità devono essere tracciabili.
Lotto e tracciabilità
Numeri di lotto, scadenza e informazioni UDI supportano una documentazione ordinata in studio.
1. Intended purpose: the most important point for PRP tubes
The key concept for medical devices is the intended purpose. It describes what the manufacturer has designed the product for and for which application area assessment, labeling and documentation apply.
This is particularly important for PRP tubes because different tubes may look similar but are not automatically intended for the same purpose.
Why intended purpose is more important than appearance
Two tubes may look almost identical and still differ significantly. What matters is not only cap color or filling volume, but the manufacturer’s documented intended purpose and the corresponding product information.
Key points to check
- regulatory classification
- material and inner coating
- additives such as sodium citrate or separation gel
- sterility and purity information
- packaging and labeling
Important for professional users
- intended application
- instructions for use or IFU
- technical documentation
- compatibility with protocol and centrifuge
- traceable LOT documentation
2. IVD tubes vs. PRP tubes as medical devices
A common mistake is to equate general laboratory or IVD tubes with PRP tubes. IVD stands for in-vitro diagnostic device. Such products are intended for diagnostic examinations outside the body, for example laboratory analysis.
IVD tubes are not automatically intended for the preparation of blood components as part of a professional PRP protocol. PRP tubes should therefore always be checked based on intended purpose, labeling and instructions for use.
Practical question
The question is not only: “Can this tube collect blood?” The more important question is: Is this tube intended and documented for this specific professional PRP workflow?
Check
- Is the tube intended for the planned preparation process?
- Is it appropriately labeled as a medical device?
- Is a suitable IFU available?
- Is a LOT or batch number present?
- Does the tube match the intended protocol and centrifuge?
3. CE marking and MDR: what professional users should check
The CE marking indicates that the manufacturer declares that the product complies with applicable European requirements. For medical devices, this is done within a conformity assessment procedure.
For PRP tubes, the CE marking should not be considered in isolation. Professional users should always check for which purpose the CE marking applies and what product documentation is available.
MDR means more than “CE”
The Medical Device Regulation sets requirements for safety, performance, risk management, technical documentation, traceability and post-market surveillance.
Useful points to check when purchasing
- CE marking on packaging or product information
- manufacturer details and responsible distributor
- instructions for use or IFU
- declaration of conformity, if available
- statement of intended purpose
- sterility information and expiry date
4. Risk class: do not state class IIa or IIb too broadly
PRP tubes are often broadly described as class IIa or IIb. This should not be generalized. The risk class always depends on the specific intended purpose, product design and applicable classification rule under the MDR.
Important
The manufacturer documentation is decisive. Product class, possible involvement of a notified body and the appropriate intended purpose should be traceable.
To check
- The class must be evident from manufacturer documentation.
- The CE marking must match the intended purpose.
- If a notified body is involved, a four-digit identification number appears next to the CE mark.
- The instructions for use should be clear.
5. Traceability: LOT, UDI and documentation
For professional users, traceability is an important quality and documentation point. LOT or batch numbers make it possible to assign a used product to a manufacturing or testing context later.
In practice, it may be useful to record the LOT number as part of internal documentation, especially when the product is used in a standardized PRP workflow.
These details should be traceable
Basic details
- article number
- LOT or batch number
- expiry date
- manufacturer
- packaging unit
Documentation
- UDI information on the intended packaging level
- product version or reference
- instructions for use
- sterility information
- storage conditions
6. Sterility, pyrogen/endotoxin testing and biocompatibility
For products that come into contact with blood or blood components, purity, sterility and material compatibility are particularly relevant quality features.
Not every sterile product is automatically suitable for every purpose. Terms such as “pyrogen-free”, “endotoxin-tested” or “biocompatible” should only be used as product properties if they are traceably documented by manufacturer information, IFU, CoA or other quality documents.
Checkpoints for professional users
- sterility and sterilization method
- pyrogen or endotoxin testing, if relevant
- biocompatibility and blood contact
- material testing and shelf life
- storage conditions and packaging integrity
7. Material quality: borosilicate glass, plastic and technical design
In addition to regulatory documentation, material and technical design also play a role. Borosilicate glass is frequently used in medical and laboratory applications due to its chemical resistance, temperature stability and mechanical properties.
Possible quality features
Material and processing
- tube material
- wall thickness and workmanship
- breakage stability within the intended centrifugation range
- closure quality
- sterile packaging
Technical details
- filling volume and vacuum
- anticoagulant, such as sodium citrate
- separation gel, if present
- clear LOT labeling
- suitable IFU
10. Legal and organizational safety for the practice
Using products that are not intended for the purpose or are insufficiently documented can raise regulatory and liability-relevant questions. Practices should therefore make their material selection traceable.
For professional users, the focus is not only on the individual tube, but on the entire documented workflow.
Useful organizational measures
- purchase from specialized suppliers
- filing product information and IFU
- documentation of article number and LOT
- regular checking of expiry dates
- alignment of tube, centrifuge and protocol
- internal SOP for PRP preparation
- training of involved personnel
8. Anticoagulante e gel separatore: non tutte le provette PRP sono uguali
Le provette PRP non differiscono solo per i documenti regolatori, ma anche per la loro struttura tecnica.
Provette PRP Vi PRP-PRO
Contengono citrato di sodio come anticoagulante e un gel separatore tissotropico. Il sistema è progettato per una preparazione PRP strutturata con chiara separazione dei componenti del sangue.

Domande frequenti su CE, MDR e provette PRP adatte
What are PRP tubes?
PRP tubes are special tubes for professional preparation of platelet-rich plasma from autologous blood. Depending on the product, they may contain anticoagulant, separation gel or other components. The manufacturer’s intended purpose is decisive.
What does CE mean for PRP tubes?
The CE marking indicates that the manufacturer declares the product complies with applicable European requirements. For medical devices, this is done as part of a conformity assessment procedure.
What does MDR mean for PRP tubes?
MDR stands for Medical Device Regulation. It is the European regulatory framework for medical devices and covers safety, performance, risk management, technical documentation and traceability.
Are laboratory tubes automatically suitable for PRP?
No. Laboratory or IVD tubes are intended for diagnostic purposes and are not automatically intended for professional PRP preparation protocols. The intended purpose of the product is decisive.
What is the difference between IVD tubes and PRP tubes?
IVD tubes are typically used to examine samples outside the body. PRP tubes for professional PRP workflows should be checked based on intended purpose, CE marking, IFU and product documentation.
Which risk class do PRP tubes have?
This cannot be answered generally. The risk class depends on intended purpose, product design and the applicable classification rule under the MDR. Manufacturer documentation is decisive.
Do PRP tubes need a UDI?
Medical devices under the MDR are subject to the UDI system. However, the UDI carrier does not always have to be directly on every individual tube and may be placed on the intended packaging level.
Why is the LOT number important?
The LOT or batch number enables product traceability. It can be recorded as part of internal practice documentation.
What does pyrogen-free or endotoxin-tested mean?
These terms refer to specific purity and testing requirements. They should only be used as product properties if they are traceably documented by manufacturer information, IFU, CoA or other quality documents.
