The NHS needs people who have recovered from coronavirus to donate blood plasma as part of a clinical trial which aims to help with the national effort against the deadly virus.
The trial will provide evidence on how effective convalescent plasma - which is plasma from people who have had coronavirus - is for treating coronavirus patients.
Adil then asked how Derek was doing.
Though Derek has now tested negative for coronavirus, he remains very ill.
Kate confirmed he is "stable" and said: "I'm learning, Adil, that stable is sometimes good."
She added: "A none down day is something to celebrate today as well."
