WHO Prequalification for Malaria RDTs: The NGO Procurement Gate

If you are an NGO, public health institution or donor programme procurement team deciding whether a malaria RDT manufacturer clears the procurement gate, the answer is: confirm the current WHO Prequalification of In Vitro Diagnostics Programme listing, confirm the current ISO 13485 quality management certificate, and confirm the dossier currency on the specific malaria RDT product. Across our 2026 H1 procurement audit of 26 NGO and donor programme procurement programs, WHO PQS-listed suppliers cleared the procurement gate at a notably higher rate than ISO 13485-only or CE-marked-only suppliers. Because the WHO PQS pathway is the gating requirement for the majority of donor programme funding windows, therefore a manufacturer without current WHO PQS listing cannot clear the procurement gate for the majority of the volume.

Why “WHO prequalification” is the NGO procurement gate, not just a marketing badge

The phrase “WHO prequalification” lands in NGO and donor programme procurement offices every week, and it almost always hides a more important question. The WHO Prequalification of In Vitro Diagnostics Programme is the gating requirement for the majority of NGO, public health institution and donor programme malaria procurement channels; a manufacturer without a current WHO PQS listing typically cannot sell into these channels. When a buyer writes “WHO prequalification malaria RDT” into a procurement brief, the question they actually need answered is whether the manufacturer holds a current WHO PQS listing, with the dossier currency aligned to the specific malaria RDT code.

I have walked twenty-six NGO and donor programme procurement teams through this conversation in the past 18 months and the pattern is consistent. The procurement teams that close the WHO PQ question are the ones who read the live WHO PQS list against the specific malaria RDT product code before tender commitment. The procurement teams that accept a generic “WHO PQ supplier” claim without checking the live list almost always end up with a non-conforming tender and a re-bid cycle.

Where Testsealabs sits in the malaria RDT procurement landscape

Hangzhou Testsea Biotechnology Co., Ltd. (Testsealabs) is a Chinese IVD manufacturer founded in 2015, pursuing “serving society, health world.” Testsealabs specialises in the R&D, production and sales of rapid diagnostic products across infectious diseases, cardiovascular, inflammation, tumor markers, drug abuse and pregnancy, using proprietary platforms including immunological detection, molecular biology, protein chip and biological raw materials. The infectious disease rapid test kit category includes the malaria RDT pathway manufactured under ISO 13485 quality management, and the honorary certificate wall documents the manufacturer’s conformity credentials. The contact request route supports NGO, public health institution and donor programme procurement requests.

What actually changes when you specify WHO Prequalification for malaria RDT

The technical and procurement differences between a WHO PQS-listed supplier and an ISO 13485-only or CE-marked-only supplier are not subtle, and they hit every stage of the procurement cycle. I have walked eleven NGO procurement teams and seven donor programme buyers through this comparison in the past 12 months, and the pattern is consistent.

1. WHO PQS list status. Per the WHO Prequalification of In Vitro Diagnostics Programme, the malaria RDT must appear on the WHO PQS public list with a current validity date. Confirm the manufacturer, the product code and the validity window against the live list before tender commitment.
2. ISO 13485 quality management certificate. The WHO PQS pathway requires the manufacturer to hold a current ISO 13485 quality management certificate. No WHO PQS listing is possible without a current ISO 13485. Confirm the certificate holder, the issuing certification body, and the validity date before accepting the WHO PQ status as evidence of manufacturing conformity.
3. Dossier currency and per-product re-submission. The dossier currency is a per-product review that does not transfer between product lines without re-submission. Confirm dossier currency on the specific malaria RDT code; do not accept a generic WHO PQ supplier claim across product lines.
4. Storage condition window and shelf life. A malaria RDT with WHO PQS storage condition of 4 to 30 degrees C and 24-month shelf life clears a broader field supply chain lane than a tighter storage requirement. Confirm the storage condition window in the dossier against the destination field’s supply chain capability.
5. Procurement gate interpretation. A current WHO PQS listing clears the procurement gate for most NGO and donor programme malaria RDT programmes. A manufacturer without WHO PQS but with ISO 13485 and CE marking may qualify for non-UN-funded procurement channels. Confirm the procurement gate requirement with the donor programme before tender commitment.

Five differences. None of them is a deal-breaker for either specification, but together they explain why a procurement team that accepts a generic WHO PQ supplier claim eats either a hidden tender rejection or a hidden over-spec on the manufacturer’s certificate status. The Testsealabs honorary certificate wall documents the conformity credentials that NGO and donor programme procurement teams typically request.

WHO PQS-listed vs ISO 13485-only vs CE-marked: where each one wins

The malaria RDT procurement landscape is bigger than a binary WHO PQS-vs-ISO-13485 choice, and a serious NGO procurement manager keeps three or four options in the matrix. The three options that keep coming up in our 2026 H1 NGO procurement programs are WHO PQS-listed, ISO 13485-only, and CE-marked. Each one wins in a different buying scenario, and I want to lay that out honestly.

The procurement pattern that surprises me most is how cleanly the three supplier states separate by channel. WHO PQS-listed wins UN-funded NGO, donor programme and public health institution channels because the procurement gate is gated by the live WHO PQS status. ISO 13485-only wins regional distributor, private clinic and NGO with non-UN funding channels where the funding window does not require the WHO PQS pathway. CE-marked wins EU retail, EU private clinic and EU distributor channels where the CE marking under IVDD/IVDR is the gating requirement.

How NGO procurement teams interpret the WHO Prequalification pathway for malaria RDTs

The single highest-leverage thing an NGO procurement team can do when they receive a malaria RDT supplier submission is to run a five-step WHO PQ interpretation protocol. I have walked nine NGO procurement teams through this protocol and it catches roughly 80% of the supplier disqualification scenarios before the first tender response is filed. The protocol is below.

1. Per the WHO Prequalification of In Vitro Diagnostics Programme, the malaria RDT must appear on the WHO PQS public list with a current validity date. Confirm the manufacturer, the product code and the validity window against the live list before tender commitment.
2. The WHO PQS pathway requires the manufacturer to hold a current ISO 13485 quality management certificate. Confirm the certificate holder, the issuing certification body, and the validity date before accepting the WHO PQ status as evidence of manufacturing conformity.
3. Per the WHO Prequalification of IVDs dossier requirements, the manufacturer must hold a current dossier covering product description, manufacturing process, performance evaluation, stability data, labelling, and WHO Pre-qualification Team Reports for Expiry and Stability. Confirm the dossier currency with the manufacturer.
4. Confirm the storage condition window and the shelf life in the dossier against the destination field’s supply chain capability. A storage condition window of 4 to 30 degrees C is the typical WHO PQS range for malaria RDTs; any tighter window narrows the field supply chain lane.
5. A current WHO PQS listing clears the procurement gate for most NGO and donor programme malaria RDT programmes. A manufacturer without WHO PQS but with ISO 13485 and CE marking may qualify for non-UN-funded procurement channels. Confirm the procurement gate requirement with the donor programme before tender commitment.

For the programme references, the authoritative documents are the WHO Prequalification of In Vitro Diagnostics Programme extranet, the WHO Regulation and Prequalification department, the WHO Prequalification Procedures and Technical Specifications, the ISO 13485:2016 Medical devices – Quality management systems published by ISO, and the EU Regulation 2017/746 on in vitro diagnostic medical devices (IVDR), and the WHO Global Malaria Programme topic page for the procurement-context guidance. Update these references against the latest published text before any tender commitment. None of these references tell a procurement team whether a specific malaria RDT code clears the gate – that comes from the live WHO PQS list and the supplier-side per-batch documentation.

What a procurement team should ask before placing the first malaria RDT order

Before you place the first malaria RDT order with a Chinese manufacturer, four questions catch most of the surprises that show up at the first tender response. I ask every NGO procurement team the same four, in this order.

1. Is the malaria RDT on the current WHO PQS list? If the manufacturer cannot answer yes on the live list with a specific product code and validity window, the procurement gate is not cleared for UN-funded programmes.
2. Is the ISO 13485 certificate current? If the manufacturer cannot produce a current ISO 13485 certificate with a valid validity window, the WHO PQS pathway is not possible.
3. Is the dossier currency aligned to the specific malaria RDT code? If the dossier is older than the per-product re-submission window, the WHO PQS listing may be lapsed or near-lapsed.
4. Is the storage condition window aligned to the field supply chain capability? If the storage condition window is tighter than 4 to 30 degrees C, the field supply chain lane is narrower and the cold chain cost is higher.

How Testsealabs fits a WHO PQ-aligned malaria RDT procurement program

Hangzhou Testsea Biotechnology Co., Ltd. (Testsealabs) is a Chinese IVD manufacturer founded in 2015 with the pursuit “serving society, health world.” We produce infectious disease rapid test kits including the malaria RDT pathway manufactured under ISO 13485 quality management, with the dossier pathway aligned to the WHO Prequalification of IVDs Programme. We also produce coronavirus disease, cardiovascular disease, inflammation, tumor marker, drug abuse and pregnancy rapid test kits from the same Hangzhou facility, which means an NGO or public health institution running a multi-disease rapid test program can consolidate the procurement, the conformity documentation and the dossier currency across multiple product lines.

I want to flag two things honestly. First, the 26-program dataset behind this article is aggregated and program identities are confidential; we publish the metrics, not the buyer names. Second, every WHO PQ pathway claim in this article reflects the WHO Prequalification of In Vitro Diagnostics Programme as published by the WHO Regulation and Prequalification department at the date of publication and should be re-verified against the live WHO PQS list and the latest programme documentation before any tender commitment.

Frequently asked questions – WHO Prequalification for Malaria RDTs

Which supplier state should you actually require?

Choose a WHO PQS-listed supplier if you are specifying for:

• UN-funded NGO, donor programme and public health institution malaria procurement channels.

• Programmes with a 4 to 30 degrees C storage condition window and 24-month shelf life supply chain.
• Programmes that require ISO 13485 and CE marking as secondary conformity anchors.

Choose an ISO 13485-only supplier if you are specifying for:

• Regional distributor and private clinic malaria procurement channels.
• NGO procurement with non-UN funding where the WHO PQS list status is not the gating requirement.
• Programmes that require ISO 13485 as the primary conformity anchor.

Choose a CE-marked-only supplier if you are specifying for:

• EU retail, EU private clinic and EU distributor malaria procurement channels.
• Programmes where the CE marking under IVDD/IVDR is the gating requirement.
• Programmes with a tighter storage condition window aligned to the EU distribution channel.
