The first thing you need to do is look at your hospital’s lab report, and see if the five items are arranged according to the regular schedule. the regular schedule should be the first item is the surface antigen, abbreviated as HbsAg. the second corresponding surface antibody is called anti-HBs, the third is the e antigen, written in English as HbeAg, the fourth is the e antibody, and it is a pair, the English should write anti-HBe. the fifth is called the core antibody, written in English as anti-HBe. The fifth one is called core antibody, which should be written in English as anti-HBc, with c being lowercase. Why is it called two and a half pairs? It is because the surface antigen and surface antibody is a pair, the patient well appear surface antibody, and then e antigen and e antibody patient condition improves, e antigen disappears, e antibody appears, is the third disappeared, the fourth appeared, and core antibody, core antibody and divided into IgG, IgM, generally some hospitals do not check, sometimes check the total antibody anti-HBc, this is the hepatitis B two and a half, because two pairs, because two pairs, surface antigen, surface antibody is a pair. Surface antigen, surface antibody is a pair, e antigen, e antibody is a pair, which is two pairs, but also a core antibody, there is no pair, so it is two pairs and a half, but also the patient to take. How to look at it? There are three columns, the first column is these symbols, the second column is the value of the test, the third column of the test sheet up the right hand side, is the normal value of 10,000. For example, if the normal value of surface antigen is less than 10, because different hospitals use different kits, the normal value is also different. So according to the hospital where the test was performed, if it is less than 10 is negative, you write this to 5, which means negative.
