Before starting GMA treatment, your doctor will ensure that you do not find yourself in a situation that contraindicates its use, at least temporarily, or requires special precautions up1.
For the procedure it is best to wear loose-fitting clothes with short sleeves or sleeves you can easily roll.
Since you will be sitting for a while, you can also bring slippers to make you more comfortable. Sweat pants with stretchy waistbands are also suitable. If you are incontinent or have an overactive bladder, you may want to consider wearing adult diapers since you won’t be able to move once the procedure begins.
Most healthcare providers will recommend that you drink plenty of fluids several days in advance of a leukocytapheresis procedure. Caffeine should be avoided as it promotes urination and can reduce the relative pressure in the veins.
On the day before the procedure, avoid any caffeinated beverages, foods (including dark chocolate), or medications (including pain relievers like Aspirin…). Eat a hearty meal prior to the procedure but not one that is large enough to cause you discomfort.
It is advisable to perform arm exercises (with weight or tensors) some days prior to the GMA session to improve venous circulation.
Avoid unnecessary blood extractions during this period.
You might want to bring something to read or watch while you are sitting (some apheresis rooms offer TV and reading materials to help pass the time).
Plan on having someone drive you home after the procedure as you may feel dizzy or faint. Though the staff will not stop you from driving yourself home, they may insist that you rest until you seem reasonably recovered.
If you have experienced body temperature (fever) before the GMA session, contact your doctor. It would be better to delay it until resolution.
