Fresh Frozen Facts Part 4: A Thoughtful Look at Plasma Transfusion by Dr. Caitlin Raymond

Caitlin Raymond, MD/PhD shared an insightful chain of posts on LinkedIn:

”Fresh Frozen Facts, Part IV: Beyond the Blood Bag

We’ve spent the last three posts unpacking the nuances of plasma as a transfusion product — thawed, typed, and delivered with varying degrees of clarity and clinical intent. But plasma’s story doesn’t stop there.

In Part IV, we explore what happens after donation — when plasma is fractionated, purified, and turned into targeted biologics that power modern hematology, neurology, rheumatology, immunology, and more.

From albumin for oncotic support to IVIG for immune modulation and Rh immune globulin for alloimmunization prevention, these plasma-derived therapies are more than just “blood products.” They’re precision tools — crafted for specific indications and held to pharmaceutical-grade standards.

We cover:

  • Albumin: when it’s the right choice — and when it isn’t
  • IVIG: how it works, when to use it, and key risks to know
  • RhIg: an elegant triumph of targeted immunotherapy
  • Hyperimmune globulins, antithrombin, C1 esterase inhibitor, and more
  • The evolving landscape of patient-centered transfusion, including care for Jehovah’s Witnesses and the legacy of hemophilia and HIV

This final installment is about precision, stewardship, and respect — for the science and the people behind every plasma product.

And if you’ve missed the earlier parts of the series, now’s the time to catch up.

Because transfusion medicine doesn’t end with a blood bag — and sometimes the most powerful plasma products don’t look like blood at all.

Caitlin Raymond, MD/PhD, has launched an educational series on Fresh Frozen Plasma (FFP), now available on her journal blog.
