APS Support UK graphic titled “Latest Research”. A stylised browser window shows the headline: “Seronegative APS: could additional antibodies help identify ‘triple-negative’ APS cases?” On the right, a green chalkboard reads “Negative” and “Positive” with a tick next to “Negative”. APS Support UK logo appears at the bottom left, with soft red blood-cell shapes in the background.
