Can the Donor Area Be Used Again?

Testing Involved in the Living Donor Evaluation Process

The following procedure is used to decide if someone can be a donor. This is a general clarification of the testing process, and may vary from center to heart:

1. A medical history review and physical examination. An extensive review of all systems, including previous illnesses and surgeries and past family medical history. Whatsoever abnormalities plant are investigated further before invasive tests are performed.
2. A financial consultation will be used to determine financial and insurance coverage for the testing process and the donation itself. Generally, if the donation is to a family member or friend, the recipient's insurance will pay for testing and surgery expenses. However, the donor might exist responsible for travel expenses (if the donor and recipient live in different towns/states) and follow-up care, in addition to lost wages. Since donors are never financially compensated, exist certain to ask the financial advisor and/or social worker at the transplant eye for aid with these issues.
3. Immunological Tests: A blood sample is taken for the following tests:
   • ABO examination to make up one's mind the donor'south claret type: O, A, B, or AB
     Please note that there are some programs that may help donor/recipient pairs with blood types that are incompatible: paired exchange and plasmapheresis.
   • Tissue typing is used to place the donor'south particular HLA antigens and determine if the donor and recipient are uniform. Each person's tissues, except for identical twins, are different from anybody else'southward. It is believed that the ameliorate the tissue lucifer, the more successful the transplant will exist over a longer flow of time

     An antigen is a genetic marker. Genetic markers are unique to your body. You may hear these called HLA, or man leukocyte antigens. The process of identifying these antigens is called tissue typing. The leukocytes, or white cells, in your claret carry these antigens and are used to identify them. More than than 7,000 to eight,000 combinations of known antigens are possible.

   • Family analysis: If an entire family unit is beingness tested, blood samples will be taken of all potential donors to decide compatibility. This takes approximately one calendar week before the results are known.
     
4. Laboratory Tests: A blood sample is taken to:
   • Appraise the hematological system
   • Assess clotting mechanism
   • Assess baseline kidney function - Glomerular Filtration Rate (GFR)
   • Screen for aberrant electrolyte remainder
   • Screen for unsuspected tendency toward glucose intolerance which might occur post-transplant with steroids
   • Screen for venereal disease
   • Screen for pancreatitis
   • Screen for liver abnormalities, which might delay the transplant until the cause is found (fluid overload, astute or chronic hepatitis)
   • Determine whether or non the patient has Hepatitis B. If HbsAB is positive (and the HbsAg is negative), the patient has developed antibodies to Hepatitis B either through vaccination or exposure.
   • Look for by or present viral activity
   • If the donor is positive for Cytomegalovirus (CMV), the recipient may need to receive Cytogam and Gancyclovir post-transplant to prevent reactivation of the disease
   • Screen for the HIV virus
5. An EKG will be performed to assess heart office.
6. A chest x-ray will be used to appraise the lungs for the presence of any abnormalities.
7. A psychological evaluation will exist used to:
   • Provide emotional back up and information to the donor
   • Assess the donor's motivation.
   • Evaluate if at that place is family unit pressure or financial incentive to donate.
   • Requite the donor an opportunity to express him or herself more than fully than she might to the medico, or with the recipient or family unit nowadays.
   • Help the staff piece of work with the donor and family prior to, and after surgery.
   • If, at whatsoever betoken in the procedure, the potential donor does not want to donate, the transplant team can assist the donor decline in a fashion that preserves the family relationships.
8. Urine Samplesare taken to:
   • Screen for kidney affliction (ACR) or any abnormalities.
   • To determine the absence or presence of a urinary tract infection.
   • Assess the amount of poly peptide excreted in a 24-hour period. An increased secretion of poly peptide would demand to be evaluated before resuming the evaluation; the creatinine clearance is to determine acceptable kidney office and to ensure that collection is an adequate 1.
9. Female person donor candidates may undergo a gynecological test and mammography.
10. An intravenous pyelography exam may be used. This examination involves an injection of dye into a vein in your arm. The dye circulates through your trunk, into your kidneys, and and so into your urinary tract. X-rays are taken to identify the structure of the kidney, veins, arteries, the ureter, and other anatomy.
11. A Helical CT Browse is done in some transplant centers. The helical CT scan is used to evaluate the internal structure of the kidney and look for the presence of cysts, tumors, etc.
12. Some transplant centers will perform a renal arteriogram if there is a question of an aberrant finding on the Helical CT Browse. The renal arteriogram is an x-ray which looks at the vasculature of each kidney: the number of blood vessels to and from each kidney, or any bear witness of vascular illness that might dominion out donation. This test requires an observation menstruum mail-exam of 6-eight hours and in some instances may require hospitalization.
