1. The PCR type of test: the test used must be a molecular PCR test for the diagnosis of active SARS-CoV-2 infection (COVID-19). No other type of test, including a rapid test, is valid,

There is one other option they will accept;
Single LAMP test instead of a PCR test and rapid test
If you show proof of a negative result from a LAMP (loop-mediate isothermal amplification) test, you do not need to provide proof of a negative result from a normal PCR test and rapid antigen test. A LAMP test is a PCR test that gives a result within 4 hours.

The following conditions apply:

You must take the LAMP test no more than 4 hours before boarding.
The result must be known before you board.

When this was introduced it was kind of a mess with especially the early flights flying back empty to AMS, but now for most flights that go the Netherlands you have the opportunity to take the rapid test at the airport.
PCR test: surely there must be several commercial parties that will guarantee PCR results the same day and/or within 24 hours.

2. If your PCR results are delayed you will not allowed to board and will be rebooked to a later flight.
