The process begins with a thorough physical examination and review of the donor’s medical history. This includes assessing the donor’s overall health, any pre-existing conditions, and past medical treatments that could affect the liver’s condition.
3.2 Blood Tests
Blood tests are conducted to evaluate liver function and detect any signs of infection or disease. Key tests include:
- Liver Function Tests (LFTs): These tests measure levels of liver enzymes (such as ALT, AST, ALP, and GGT), bilirubin, and albumin to assess liver function and detect any damage or inflammation.
- Viral Serology: Tests for hepatitis B, hepatitis C, HIV, and other viruses are performed to ensure the liver is free from infection.
- Coagulation Studies: Prothrombin time (PT) and international normalized ratio (INR) are measured to assess the liver’s ability to produce clotting factors.
3.3 Imaging Studies
Imaging studies provide detailed views of the liver’s structure and identify any abnormalities. Common imaging techniques include:
- Ultrasound: This non-invasive technique uses sound waves to create images of the liver, detecting tumors, cysts, or other structural abnormalities.
- CT Scan: Computed tomography (CT) scans provide cross-sectional images of the liver, offering detailed information about its size, shape, and any lesions present.
- MRI: Magnetic resonance imaging (MRI) uses magnetic fields and radio waves to create detailed images of the liver, particularly useful for detecting small tumors or assessing liver fibrosis.
3.4 Liver Biopsy
A liver biopsy involves taking a small tissue sample for microscopic examination. This helps assess the liver’s cellular structure, detect fibrosis (scarring), inflammation, and other abnormalities that may not be visible through imaging studies.
3.5 Perfusion Assessment
During the transplantation process, the liver’s perfusion (blood flow) is assessed to ensure it is adequately supplied with oxygen and nutrients. This can be done visually and through blood flow measurements.
3.6 Donor Risk Assessment
The donor is evaluated for any risk factors that could affect the liver’s viability, such as age, obesity, alcohol use, and history of liver disease. These factors are carefully considered to determine the suitability of the liver for transplantation.
By combining these comprehensive assessment methods, transplant teams can make informed decisions about the health and viability of a liver, maximizing the chances of a successful transplant outcome.
4. What Role Does Liver Function Play in Determining Its Worth?
Liver function plays a crucial role in determining the worth of a liver, particularly for transplantation and research purposes. The liver’s ability to perform its vital functions directly impacts its value and suitability for these applications.
4.1 Metabolic Functions
The liver is responsible for metabolizing drugs, hormones, and other substances. Its efficiency in performing these metabolic processes is critical. Impaired metabolic function can reduce the liver’s value, especially for transplantation, as it may not adequately process medications and toxins in the recipient’s body.
4.2 Protein Synthesis
The liver synthesizes essential proteins, including albumin and clotting factors. Albumin helps maintain fluid balance in the bloodstream, while clotting factors are necessary for blood coagulation. Deficiencies in protein synthesis can lead to edema, ascites, and bleeding disorders, reducing the liver’s viability.
4.3 Bile Production
The liver produces bile, which is essential for fat digestion and absorption. Impaired bile production can lead to malabsorption of fats and fat-soluble vitamins, affecting overall nutritional status. A liver with poor bile production is less desirable for transplantation.
4.4 Detoxification
The liver detoxifies harmful substances from the blood, including ammonia, bilirubin, and waste products. Inefficient detoxification can lead to the buildup of toxins in the body, causing hepatic encephalopathy and other complications. A liver with compromised detoxification capabilities is less valuable.
4.5 Immune Function
The liver plays a role in immune function by filtering bacteria and other pathogens from the blood. Impaired immune function can increase the risk of infection, making the liver less suitable for transplantation.
4.6 Regeneration Capacity
The liver has a remarkable ability to regenerate after injury. This regenerative capacity is an important factor in determining its worth, especially for partial liver transplants or resections. A liver with good regenerative potential is more valuable.
4.7 Liver Function Tests (LFTs)
Liver function tests (LFTs) are used to assess the liver’s ability to perform these critical functions. Abnormal LFT results, such as elevated liver enzymes (ALT, AST, ALP, GGT), high bilirubin levels, or low albumin levels, indicate impaired liver function and can significantly reduce its worth.
In summary, the liver’s ability to perform its metabolic, synthetic, excretory, and immune functions is paramount in determining its worth. Comprehensive assessment of liver function through LFTs and other evaluations is essential for determining its suitability for transplantation and research.

These policies aim to allocate livers based on medical urgency, geographic equity, and efficient use of resources.
6.2 Medical Urgency
Medical urgency is a primary factor in liver allocation. The Model for End-Stage Liver Disease (MELD) score is used to assess the severity of chronic liver disease in adults. The MELD score incorporates bilirubin, creatinine, and INR levels to estimate the three-month mortality risk. Higher MELD scores indicate greater urgency and higher priority for transplantation.
6.3 Pediatric Allocation
For pediatric patients, the Pediatric End-Stage Liver Disease (PELD) score is used to assess medical urgency. The PELD score includes bilirubin, INR, albumin, growth failure, and age to estimate mortality risk in children with liver disease.
6.4 Geographic Equity
Geographic equity is considered to reduce disparities in access to liver transplantation across different regions. Livers are initially offered to candidates within the local donation service area (DSA), then to candidates in broader geographic regions if no suitable match is found locally.
6.5 Waiting List
Patients with liver disease are placed on a waiting list after evaluation by a transplant center. The waiting list ranks candidates based on their MELD or PELD scores, blood type, body size, and other factors. When a liver becomes available, the transplant center identifies potential recipients based on the allocation criteria.
6.6 Matching Process
The matching process involves comparing the donor’s liver characteristics (such as blood type, size, and quality) with the recipient’s characteristics. Compatibility is essential to minimize the risk of rejection. Crossmatching may be performed to detect pre-existing antibodies that could cause immediate rejection.
6.7 Organ Procurement Organizations (OPOs)
Organ Procurement Organizations (OPOs) play a critical role in the allocation process. OPOs are responsible for recovering organs from deceased donors and coordinating their distribution to transplant centers. They ensure that organs are allocated according to OPTN/UNOS policies.
6.8 Appeals Process
An appeals process is in place to address any concerns or disputes related to the allocation of livers. Transplant candidates or their representatives can appeal allocation decisions if they believe the policies were not followed correctly.
The allocation of livers for transplantation is a carefully regulated process designed to prioritize patients with the greatest medical need while ensuring fairness and efficiency.
