Common Misconceptions

10 misconceptions. 10 clear answers.

A successful donation begins well before you walk through the center’s doors. A few simple steps are all it takes to ensure that your experience is comfortable and that your blood is collected under the best possible conditions.

Myth:

"I didn't sleep, so I've lost blood and I can't donate!"

Lack of sleep does not reduce the amount of blood in the human body. Not having slept does not prevent you from giving blood.

Myth:

"If I give blood, I might become weak!"

No, giving blood does not automatically make you weak. It causes no harm to the donor’s health.

Myth:

"If I give my blood, they will take my soul!"

Scientifically speaking, the soul is not part of the anatomy of the human body.

Myth:

"Can you pass on your genes to someone by giving blood?"

Scientifically, no. No transmission of temperament, feelings, character traits, or anything similar has ever been proven.

Myth:

"My church forbids me from giving blood!"

The faith or religious beliefs of the person expressing this idea must be respected, but blood can only be replaced by blood.

Myth:

"What should I eat or drink after giving blood?"

You should eat and drink normally.

Myth:

"Are the tests performed on the blood reliable?"

The tests performed on every unit collected are reliable and guarantee the safety of recipients.

Myth:

"I have my period, so I won't give blood!"

As a rule, giving blood at the start of your period is not recommended.

Myth:

"I have the flu, so I won't give blood."

The flu is a viral infection, and giving blood during the infection is not advised.

Myth:

"I have a migraine, so I won't give blood!"

After the clinical checks, we will determine whether the person is fit to donate.
