Manual Processing for Low Volume Cord Blood
Kathryn Cross, CEO of Anja Health, on the future of stem cell therapy
The real point is that low collection volume can make or break the usefulness of a banked cord blood unit, so processing method becomes a core product feature, not just a back office lab choice. In cord blood banking, more recovered stem cells means a stronger transplant dose later. Anja is positioning manual processing as a way to rescue small collections, especially below 40 mL, by letting technicians adjust the workflow instead of running every sample through the same automated path.

This matters because transplant quality is tied to cell dose. Industry materials across private banks emphasize total nucleated cells and CD34 positive stem cells as key outputs, and low starting volume usually means fewer cells to work with unless the lab can preserve more of them during separation.
-
The competitive wrinkle is that there is no single industry standard. Anja frames manual processing as better for very small samples. ViaCord also says manual hetastarch processing allows custom treatment of each unit. By contrast, many banks market automated systems like AXP for sterility and consistency, while Cryo-Cell markets PrepaCyte as a manual or semi manual method that performs especially well on low volume units.
-
That makes Anja's claim less about inventing a new lab method and more about choosing a side in a real workflow tradeoff. Automated systems are easier to standardize at scale. Manual handling gives technicians more room to adapt when the sample is small or messy, which fits Anja's broader pitch of combining lower priced consumer packaging with higher touch lab work.
Going forward, cord blood banks will compete less on storage alone and more on recoverable cell dose, collection success under delayed clamping and low volume births, and whether parents trust the lab to preserve a usable sample. If Anja can keep pairing consumer friendly pricing with credible cell recovery claims, it can carve out a differentiated position against older, more standardized banks.
