Hepatitis B
Hepatitis B is a liver infection caused by the hepatitis B virus. The testing offered by Better Life Science looks for the hepatitis B surface antigen (HBsAg). This can be found in high levels during acute or chronic hepatitis B infection. HBsAg usually means that the person is infectious. In some cases it can also be found within 30 days after hepatitis B vaccination.

Hepatitis C
Hepatitis C is a liver infection caused by the hepatitis C virus (HCV) and is primarily transmitted through blood-to-blood contact. It can be either acute (short-term) or chronic (lifelong), with many people showing no symptoms or having mild symptoms initially. Untreated, chronic hepatitis C can lead to serious complications like liver scarring (cirrhosis), liver failure, and liver cancer.

HIV 1/2
HIV, or human immunodeficiency virus, is a virus that attacks the body’s immune system and can lead to AIDS (acquired immunodeficiency syndrome). This test screens for HIV 1/2 antibody as well as the HIV-1 p24 antigen.

Hepatitis B

Acute infection symptoms (can appear 1–4 months after exposure):

• Fatigue and weakness
• Loss of appetite
• Nausea and vomiting
• Abdominal pain (especially near the liver)
• Dark urine
• Clay-colored stool
• Joint pain
• Jaundice (yellowing of the skin or eyes)
• Mild fever

Chronic infection:

• Often asymptomatic for years
• May show ongoing fatigue, mild abdominal pain, or elevated liver enzymes
• Long-term risk: cirrhosis, liver failure, and liver cancer

Hepatitis C

Acute phase (within 2–12 weeks after exposure):

• Often no symptoms
• When present: fatigue, nausea, fever, joint pain, dark urine, light-colored stool, jaundice

Chronic phase:

• Frequently asymptomatic for decades
• Possible ongoing fatigue, depression, or right-upper-quadrant discomfort
• Over time: cirrhosis, liver failure, or hepatocellular carcinoma

HIV (Human Immunodeficiency Virus)

Acute HIV infection (2–4 weeks after exposure):

• Fever and chills
• Fatigue
• Rash (often generalized)
• Sore throat
• Swollen lymph nodes
• Muscle and joint aches
• Night sweats

Chronic HIV infection (as virus persists):

• Often no obvious symptoms for years
• Ongoing swollen lymph nodes, weight loss, recurrent fevers, or infections

Advanced HIV / AIDS stage:

• Marked immune suppression
• Frequent severe infections (opportunistic infections)
• Significant weight loss
• Chronic diarrhea
• Neurologic symptoms or cancers (Kaposi’s sarcoma, lymphoma, etc.)

You should consider getting tested if:

• You become sexually active
• You have had unprotected sex
• You are experiencing symptoms of a sexually transmitted infection
• You are entering into a new sexual relationship
• You have received a notification from a previous partner that they are infected

If you are experiencing symptoms, have been informed by a partner that they have a sexually transmitted infection, or if you have any concerns, you should follow up with a healthcare provider.
