Dear Sir or Madam:

Re: [Patient’s Name & Address]

The above named is a person with a bleeding disorder called [Name of Bleeding Disorder], and is travelling to [Location, Country]. The bleeding to which [he/she] is subject can only be controlled with a transfusion of plasma or recombinant concentrate. It would not be possible for [him/her] to travel without a supply of concentrates. [He/She] carries with [him/her] sufficient units for self-infusion as maintenance therapy and additional amounts in the event of an emergency. [He/She] also carries the syringes, needles etc., necessary for infusion. The prescribed drugs [Drug1, Drug2, ...] are also being carried for management of [medical condition(s)].

A customs official who inadvertently withholds bottles of human plasma or recombinant concentrate may place [Patient’s Name]’s life in jeopardy. For purposes of comparison, it is as if insulin vials were withheld from a person with diabetes.

In anticipation of your cooperation, I am,

Yours very truly,

[Doctor’s Signature]
[Doctor’s Name & Position]
