This study is looking at a new way to collect blood samples using a device called Tasso+. We want to see if blood collected with the Tasso+ device gives the same results as traditional blood draws (from a vein) for a complete blood count (CBC). You might be able to join if you are at least 18 years old, need a CBC as part of your regular care, and have abnormal blood cell counts like leukopenia (low white blood cells), leukocytosis (high white blood cells), or neutropenia (low neutrophils). We will compare the white blood cell and absolute neutrophil count results from both collection methods. This study is currently unclear on its recruitment status and plans to enroll at least 40 participants.

Study design

This is an observational study comparing two blood collection methods. It aims to enroll at least 40 participants.

What's involved

You would provide blood samples using both the Tasso+ device and a traditional venous blood draw. You will also complete a survey about your experience with the Tasso+ device.

Compensation

Not stated in the trial record.

Follow-up

Adverse events will be evaluated up to 24 hours after using the Tasso device.
