Different detection methods: Different hospitals may use different detection methods, such as chemiluminescence and enzyme-linked immunoassay. And the sensitivity and accuracy of these methods may be different, resulting in different results.
Different detection time: If the detection time of two hospitals is different, such as a few days or weeks apart, the results may be different due to the dynamic changes of the virus in the body.
Different sample treatments: Samples may be treated differently during collection, treatment and detection, such as storage mode and transportation time, which may affect the accuracy of the results.
Difference between instruments and reagents: Different instruments and reagents may affect the test results, such as sensitivity and specificity.
Different interpretation criteria: different doctors or laboratories may interpret the results differently, such as the criteria for judging positive and negative.
There is indeed a big gap between the test results of the two hospitals you provided. Among them, the large difference in surface antibody values may be due to the different detection methods or reagents used in the two hospitals. The great difference between E antibody and core antibody may be due to the different testing standards in different laboratories.
It is suggested that you can consult doctors or laboratory staff in two hospitals to find out the detection methods, reagents and interpretation standards they use, so as to help you better understand the reasons for the difference in results. At the same time, if conditions permit, we can also carry out multiple tests in the same hospital to obtain more accurate quantitative data.
