HEPATITIS B SURFACE ANTIGEN (HBsAg), QUANTITATIVE

QUANTITATIVE HBSAG MEASUREMENT IS A CRUCIAL DIAGNOSTIC TEST FOR HEPATITIS B VIRUS (HBV) INFECTION. IT MEASURES THE AMOUNT OF HBSAG PRESENT IN THE BLOOD, A PROTEIN FOUND ON THE SURFACE OF THE HBV VIRUS. A POSITIVE HBSAG RESULT INDICATES CURRENT INFECTION. THE QUANTITY OF HBSAG CAN HELP DETERMINE THE STAGE OF INFECTION AND MONITOR TREATMENT RESPONSE. HIGHER LEVELS OF HBSAG MAY SUGGEST ACTIVE VIRAL REPLICATION AND INCREASED RISK OF DISEASE PROGRESSION. HOWEVER, ITS IMPORTANT TO NOTE THAT HBSAG LEVELS DO NOT ALWAYS CORRELATE DIRECTLY WITH DISEASE SEVERITY.
