The Blood Donation Process

The entire process takes about 1 hour, but the actual donation is only 8-10 minutes.

1

Registration

You'll fill out a health questionnaire and provide basic information. This helps ensure your safety and the safety of recipients.

2

Health Screening

A medical professional will check your vital signs (blood pressure, pulse, temperature) and test your hemoglobin level using a small finger prick.

3

Donation

You'll be seated comfortably. A sterile needle is inserted into your arm, and approximately 450ml of blood is collected. The process takes 8-10 minutes.

4

Recovery

After donation, you'll rest for 10-15 minutes and enjoy refreshments. This helps your body adjust and prevents dizziness.

Safety First

All equipment used is sterile and disposable. Each donor receives a new, unused needle that is discarded after use. The process is supervised by trained medical professionals.

After Donation: Recovery and Care

  • Rest: Sit or lie down for 10-15 minutes
  • Have refreshments: Drink juice or water and eat a light snack
