Editor’s note: Bloodworks updated the time it will be at St. Barbaras in Black Diamond. The article has been updated.

Bloodworks Northwest is coming back to Black Diamond.

The non-profit will be collecting blood at the city’s St. Barbara Catholic Church (32416 6th Ave.) on Jan. 14 from 10 a.m. to 5 p.m., and Jan. 15 from 9 a.m. to 5 p.m.

Bloodworks says January is one of the most challenging months for blood donations.

“Extreme cold weather and seasonal illnesses often make it difficult for Bloodworks to maintain a sufficient blood supply at this time of year,” the organization said in a press release. “Make your appointment to help us keep a stable blood supply through this season.”

Blood isn’t the only thing being collected at these pop-up donor centers — the church’s Knights of Columbus is collecting canned goods during the blood drive for their own food bank, as well as others on the Plateau.

Before you sign up to donate blood, though, there are several more rules to adhere to due to the pandemic.

Maybe most importantly, walk-in appointments are no longer allowed — Bloodworks Northwest is requiring everyone to schedule an appointment by calling 800-398-7888 or by visiting their website, www.bloodworksnw.org.

Additionally, no guests or children under the age of 16 are allowed onsite.

Masks are also required in order to donate.

Although the time it takes to donate blood differs from person to person, Bloodworks Northwest encourages donors to plan for an hour-long appointment, which includes signing in and preparation for donating blood.
