Hello and thanks for posting,

Unfortunately, our service is not out of hours, as the nurses respond between 9 to 5pm weekdays.

As I understand, this anticardiolipin antibody (aCL) blood test looks at levels of cardiolipin antibodies. These antibodies can affect how the blood clots. 

It seems that sometimes the actual cancer, or some drugs, or an infection, can cause the levels to change. You will need to speak to the hospital team directly about this, as they are best placed to comment in more depth.

I hope that you get to find out more soon, 

Kind regards,

Vanda
