Leslie Sinclair has been a committed donor who has given over 100 pints of blood in the last five decades, but he was recently turned away from donating blood for refusing to answer if he had been pregnant.

On his most recent trip to the Albert Halls clinic in Stirling, Scotland, Mr. Sinclair was prohibited from donating after he refused to answer a question on a form asking if he was pregnant. As a man in his 60s, the question is nonsensical in many ways. 

Sinclair said the clinic staff indicated they could not accept his blood unless he responded to that question. The staff argued that it is not always clear if someone is pregnant, and the policy is in place to "promote inclusiveness." 

The national health policy states that pregnant women or those with a baby not yet six months old are not allowed to give blood.

Sinclair argued that there had never been an issue with donating blood, something he has done for more than four decades. 

In an interview, he told The Daily Mail, "There is always a form to fill in, and that's fine… they tend to ask about medical conditions or diseases… to be safe."

"This time around, there was a question I hadn't seen before: 'Are you pregnant, or have you been in the last six months?' which required a yes or no answer.," he continued.

"It is nonsensical, and it makes me angry because there are vulnerable people waiting for blood, including children, and in desperate need of help. But they've been denied my blood because of the obligation to answer a question that can't possibly be answered."

The director of the Scottish National Blood Transfusion Service, Marc Turner, said: "We appreciate the support of each and every one of our donor community and thank Mr. Sinclair for his commitment over a long number of years."
