Cord Blood Banking 5

Question 1

Which financial structure do most private cord blood banks use to fund long-term storage costs?

Accepted Answer

Upfront processing fees combined with annual storage fees

Answer

Private banks typically charge a one-time collection and processing fee ($1,500–$2,500) plus annual storage fees ($100–$300) to cover ongoing operational costs.

Question 2

A physician recommends cord blood banking to a family with a child who has leukemia. Which banking type is most appropriate?

Accepted Answer

Directed donation or private banking for a sibling match

Answer

When there is an existing sick sibling who may need a transplant, directed donation or private banking ensures the unit is reserved and accessible for that specific patient.

Question 3

Which statement about delayed cord clamping and cord blood collection is accurate?

Accepted Answer

Delayed clamping increases blood flow to the infant, reducing the volume available for banking

Answer

Delayed cord clamping allows more blood to transfer to the newborn, which is beneficial for the infant but reduces the volume available for cord blood banking.

Question 4

What does 'viable CD34+ cell recovery' measure when a cord blood unit is thawed before transplant?

Accepted Answer

The proportion of CD34+ cells still alive and functional after cryopreservation

Answer

Post-thaw viability of CD34+ cells confirms the unit retained functional stem cells through the freeze-thaw cycle, which predicts engraftment success.

Question 5

Under which circumstance is an autologous cord blood transplant NOT a valid option?

Accepted Answer

The patient develops a genetic disease present at birth, such as sickle cell disease

Answer

Autologous units cannot treat genetic diseases present at birth because the cord blood carries the same genetic defect as the patient's existing cells.
