Specimen Required

NONE

Fasting Required

Purpose of the Test

The washed RBC pack cell test is not a diagnostic test for a specific medical condition. It is a test to ensure that red blood cells are free of plasma proteins before transfusion to prevent transfusion-associated reactions in certain patient populations.

When this test is required

The use of washed RBC pack cells is indicated in patients who have experienced severe allergic reactions to blood products or who have certain medical conditions that require the removal of plasma proteins from the transfused blood product.

What the Test Detects

The test is performed on packed red blood cells, which have been washed to remove plasma proteins. The test confirms the absence of plasma proteins, indicating that the washing process was effective.

Preparation for the Test

There is no specific preparation required for this test.

Sample Requirements

A sample of packed red blood cells is required for the test.

Additional Notes

Washing red blood cells is a time-consuming process, and not all blood banks may have the capability to wash the red blood cells. The use of washed RBC pack cells is specific to certain patient populations, and not all patients require this type of transfusion. The healthcare provider ordering the transfusion will determine if washed RBC pack cells are necessary for the patient’s medical condition.
