Jasmine Langham is considered a "good egg" by the Australian Red Cross blood service.
With a low number of appointments at the Launceston Donor Centre over the Easter and Anzac Day public holidays, the service is calling for more good eggs to come forward and help.
On Wednesday Ms Langham made her first plasma donation, after giving blood for the first time last year.
She said it felt good to know she was helping people and making a difference.
"I always knew it was a great thing to do, because there are so many people out there who are sick and need good quality blood," she said.
"It is so easy really and last time I gave blood I got a text saying my blood had been used to save lives in Victoria.
"It feels really good knowing you are helping."

The Launceston centre needs about 70 extra donors between Easter Saturday and Saturday April, 27 including Anzac Day, to help bolster supplies for cancer and road trauma patients.
Blood Service spokesperson Ann Harvey said that Easter was one of the most challenging times of the year to collect blood.
"The need for blood never takes a break, yet we know that donor numbers are traditionally low at Easter" she said.
"A component of blood called platelets has a shelf life of only five days, so it's important that blood is donated over and immediately after the Easter break.
"Cancer patients in particular rely upon platelets to help them through their chemotherapy treatments."
One in three Australians will need blood or a blood product in their lifetime.

Along with its regular opening hours, the Launceston centre will be open until 3pm on Easter Saturday, Easter Monday and Anzac Day.
