Organ transplant complications are serious medical issues that occur after transplant surgery, including organ rejection, life-threatening infections, and medication side effects. These complications are caused by immunosuppressive medications that weaken the immune system, making recipients vulnerable to infections like cytomegalovirus (CMV), Epstein-Barr virus, and bacterial infections. The Cytomegalovirus (CMV) Antibodies IgG test is the most important test for organ transplant recipients because CMV infection is the leading infectious complication that can trigger transplant rejection.

Organ transplant complications are caused by immunosuppressive medications that patients must take for life to prevent rejection of the new organ. These medications deliberately weaken your immune system so it won't attack the transplanted organ, but this also makes you highly vulnerable to infections from viruses like cytomegalovirus (CMV), Epstein-Barr virus, and bacteria. Additionally, the transplanted organ itself may be rejected if your immune system recognizes it as foreign tissue, causing inflammation and damage. Other complications arise from medication side effects including kidney damage, high blood pressure, diabetes, and increased cancer risk.
The Cytomegalovirus (CMV) Antibodies IgG test is the most important test for organ transplant recipients because CMV infection is the leading cause of serious post-transplant complications and rejection. This blood test detects IgG antibodies that indicate past or active CMV infection, which can cause pneumonia, hepatitis, and damage to the transplanted organ. High levels of CMV IgG antibodies signal an infection that requires immediate treatment to prevent life-threatening outcomes. Transplant recipients also need regular monitoring with comprehensive metabolic panels to check organ function, complete blood counts to monitor for medication side effects, and immunosuppressant drug level tests to ensure medications are in the therapeutic range.
You should get tested if you've received an organ transplant and experience fever, fatigue, unusual tiredness, or flu-like symptoms that could indicate infection. Get immediate testing if you notice decreased urine output (for kidney transplants), shortness of breath (for heart or lung transplants), jaundice or abdominal pain (for liver transplants), or any signs your transplanted organ isn't functioning properly. All transplant recipients require regular blood testing on a schedule determined by their transplant team, typically very frequently in the first months after surgery, then gradually less often but continuing for life. You should also get tested before any scheduled follow-up appointments or if your doctor adjusts your immunosuppressive medications.

What this means
Your testosterone levels are slightly below the optimal range. While this is not necessarily cause for concern, it may contribute to occasional fatigue, reduced motivation, or lower muscle mass over time.
Recommended actions
Increase resistance or strength training
Prioritize 7–8 hours of quality sleep per night, try to reduce stress
Include more zinc- and magnesium-rich foods (like shellfish, beef, pumpkin seeds, spinach)
Consider retesting in 3–6 months
