Preventative Health Platform Reveals Hidden Metabolic Risk

Hepatitis B and C are viral infections that affect the liver and can lead to serious health complications if left untreated. Both infections can be detected through laboratory blood tests, which are essential for early diagnosis and treatment. Hepatitis B is caused by the hepatitis B virus (HBV), while hepatitis C is caused by the hepatitis C virus (HCV). These viruses spread primarily through contact with infected blood or bodily fluids, and many people with these infections may not experience symptoms for years, making routine testing particularly important for at-risk populations.

Laboratory testing for hepatitis B typically involves several different blood tests. The hepatitis B surface antigen (HBsAg) test detects the presence of the virus and indicates an active infection. The hepatitis B surface antibody (anti-HBs) test shows whether a person has developed immunity to the virus, either through vaccination or recovery from a past infection. The hepatitis B core antibody (anti-HBc) test indicates whether someone has been exposed to the virus at some point. Additional tests may measure viral load and liver function to assess the severity of infection and guide treatment decisions.

For hepatitis C, the initial screening test is the hepatitis C antibody test, which detects antibodies produced by the immune system in response to HCV infection. A positive antibody test means a person has been exposed to the virus at some point but does not necessarily indicate an active infection. If antibodies are detected, a follow-up test called the HCV RNA test is performed to determine if the virus is currently present in the blood. This molecular test can also measure the amount of virus in the bloodstream, known as the viral load, which helps doctors monitor the infection and response to treatment.

People who should consider hepatitis B and C testing include healthcare workers, individuals who inject drugs, people with multiple sexual partners, those receiving dialysis, individuals born to mothers with hepatitis, and anyone who has received blood transfusions or organ transplants before widespread screening began. Testing is also recommended for people with elevated liver enzymes or symptoms of liver disease. Early detection through laboratory testing allows for timely treatment, which can prevent serious liver damage, cirrhosis, and liver cancer. Modern antiviral treatments are highly effective at managing these infections and, in the case of hepatitis C, can often cure the infection completely.
