( CNN ) A Canadian couple has reached out to the Internet to help save their twin 3-year-olds . Binh and Phuoc Wagner both require a liver transplant to survive . The problem is that their father , Michael Wagner , can donate to only one of the pair . Wagner and his wife , Johanne , have taken their search for a second donor to social media , establishing a Facebook page , Liver Transplants for our Vietnamese Twin Girls , which has garnered more than 5,000 likes as of Monday afternoon . The Kingston , Ontario , couple also has a blog , One More Potato in the Pot , about their lives with nine children , four of whom are adopted . `` We need people to come forward , people who are willing to be assessed to be live liver donors , '' Johanne Wagner told CBC News on Sunday . `` Things could turn around very quickly on us , and their condition could get worse . '' The twins were adopted from Vietnam in November 2012 , when they were 18 months old . The pair are afflicted with Alagille syndrome , a genetic disorder that causes liver damage because of bile duct abnormalities , according to the National Institutes of Health 's Genetics Home Reference . Among other issues , the ailment causes the twins to itch severely -- enough that they scratch while they sleep , creating sores . The Wagners ask interested parties to contact the following : . Toronto General Hospital ( UHN ) Living Donor Assessment Office . 416-340-4800 ext . 6581. and specify that you are willing to be assessed to donate to either Thi Binh La or Thi Phuoc La ( date of birth May 14 , 2011 ) . You can also go to this website . or print the Donor Health History and fax it to 416-340-4317 . `` When we went to Vietnam , before we went , we knew that they were very ill , and we knew it was liver-related , '' Michael Wagner told CBC News . `` We said , 'All right , we 're committed , and we 're going to move forward with the hope that everything is going to be OK. ' `` The Wagners have been updating their Facebook page since establishing it December 26 . What 's needed , they say , is someone who meets the following qualifications : . 1 ) be older than 18 and younger than 60 . 2 ) be in good overall health and physical condition . 3 ) have a compatible blood type : A or O ( rhesus factor positive or negative does not matter ) . 4 ) have a BMI of less than 35 to be worked up for consideration and no greater than 32 at the time of surgery ( transplant ) . Livers do regrow , but a donor would have to be in a hospital for several days and take another few weeks to recover . In the meantime , the Wagners and the girls ' doctors are monitoring the situation . If things take a turn for the worse , the twins ' doctor Dr. Binita Kamath told CBC News , the girl who will receive Michael Wagner 's liver will be chosen based on immediate need . `` I think we will make the decision based on facts and keep it as dispassionate as possible , '' she said . `` We feel comfortable making this decision . ''
The twins need liver transplants , or they 'll die . The girls are afflicted with Alagille syndrome ; their father can help just one .
