Interested to learn more about the effect of your COVID-19 vaccination?

New in stock: the Rapid SARS-CoV-2 Neutralizing Antibody Test!

This test is especially designed for the evaluation of the effect of your vaccination against COVID-19!

How does it work?

People infected with COVID-19 generate neutralizing antibodies to SARS-CoV-2. These functional antibodies will combine with spiked proteins on the surface of SARS-CoV-2 to prevent further (re)infection. A similar thing happens when you are vaccinated against COVID-19. Neutralizing antibodies neutralize the virus virulence and it’s alleviating disease symptoms, which will reduce the mortality of infected people on the long run.

You can find the product on our website via this link (for health care professionals only).


Infographic neutralizing antibodies

Validatie door Nederlands MM lab laat zien dat de InTec SARS-CoV-2 antigeen sneltest ruim binnen de WHO criteria uitkomt.


Zelfs in grotendeels mild-symptomatische populatie laat prospectieve validatie door Nederlands klinisch MM lab zien dat de InTec SARS-CoV-2 antigeen sneltest ruim binnen de WHO criteria uitkomt.

De studie staat nu vermeld op de RIVM website en is op aanvraag in zijn geheel beschikbaar, net als de directe vergelijkingen met Roche en Abbott Ag sneltesten.

Voor alle teststraten en professionele gebruikers van antigeen sneltesten betekent het een kwalitatief sterke toevoeging aan het testarsenaal, tegen een acceptabele prijs.

SARS-CoV-2 Antigen rapid tests on stock now

We are happy to announce the high quality InTec rapid antigen tests are now available from our warehouse in The Netherlands

Launch of rtPCR Kit for B.1.1.7 strain of SARS-CoV-2 (UK strain)

The kit uses a technique termed multicolor probe melting curve analysis, which allows for multiple mutations to be identified in a single reaction tube on a real-time PCR instrument. By using the combinations of different melting temperature curves generated via differently fluorophore-labeled probes, each mutation can be identified through a post-PCR melting curve analysis. Of the 9 different mutations on the spike protein (N501Y, A570D, D614G, P681H, T716I, S982A, D1118H, Y144del and HV69-70), four mutations (N501Y, D614G, HV69-70 and Y144del) were used as the detection targets. When these four mutations simultaneously occur, a B.1.1.7 strain can be confirmed as proven by a bioinformatics study.

Antigen rapid test evaluated in VTM by Microbe&Lab: 93 % sensitivity and 100% specificity

InTec’s new rapid test for SARS-CoV-2 was evaluated by Microbe&Lab in Amsterdam on 50 positive PCR samples and 50 negative PCR samples.

All samples were taken from a VTM sample bank. Full report available on request

Performance on fresh samples may be expected to be even better, which will be the objective to validate in the coming weeks.

The new tests will be on stock from January 27, 2021.

Turnkey PCR labs

In the months November and December, ProDiag successfully supplied complete rtPCR labs to clients in The Netherlands, Hungary, Romania, Kosovo and others.

Turn-key means we cover all process steps:

  • collection (swabs and saliva)
  • extraction (instruments and reagents)
  • cycling/reading (instruments and reagents)

Plus basic lab accessories:

  • laptop
  • freezer
  • vortex
  • centrifuge
  • transparent rtPCR tube strips with caps
  • pipettes and pipette tips

Saliva as an easy-to-collect material is showing promising progress in SARS-CoV-2 Virus RNA collection

Chief Executive Officer at ProDiag BV and DTwist BV

Lowering thresholds to participate in testing programs is receiving attention, both in terms of convenience for the general public and in terms of lowering the need for trained collection staff.

ProDiag is proud to announce to have started the delivery of 180.000 saliva collection sets to the Dutch Ministry of Health, Welfare and Sports. These sets will be used especially for painless sampling with children, for which the virus collection with (large) swabs is an even bigger challenge than for adults.

Research groups comparing SARS-CoV-2 detection between patient-matched nasopharyngeal- and saliva samples conclude that saliva samples

  • Show less variability in self-sample collection
  • Show a greater detection sensitivity and greater consistency throughout the course of infection
  • Provide earlier detection of viral RNA at onset of symptoms and is even detectable before onset of fever or respiratory symptoms

We will be happy to provide you with the underlying publications.

We assume saliva will increasingly be used as the collection method of choice as input to rtPCR testing in labs.

ProDiag is now a member of Diagned

ProDiag has been accepted as a new member of Diagned, the Dutch Association of manufacturers and distributors of in vitro diagnostics products.

We look forward to a stimulating partnership with Diagned professionals!

First 500,000 InTec’s rapid tests arrived in Europe

ProDiag BV has received its first shipment of 500,000 of InTec’s SARS-CoV-2 IgM/IgG antibody rapid tests!

Next shipments are lined up. It shows China’s NMPA and Ministry of Commerce have stepped up their role in granting export licenses for validated products only.

We base our Instructions For Use on a study performed at the CDC in Wuhan (n=454), resulting in a 94,4% sensitivity and 98% specificity. We are actively pursuing to add more data to this dataset.

InTec has been a specialized manufacturer of rapid tests in infectious diseases for 30 years and had 2 other rapid tests (HIV and HCV) succesfully pass the WHO Pre-Qualification program. This means that technical files, quality system and production sites have passed WHO teams’ audits.

We strongly believe launching products should be done in a responsible way. InTec’s test has therefore been entered into evaluations at China CDC locations, FIND, US FDA EUA, Erasmus Medical Center, RIVM, WHO EUL and many others.

Although interim reports on partial data sets are circulating, full study reports will come out soon.

This test is delivered to medical professionals and sub-distributors only.

We are proud to contribute in the fight against COVID19!
