HBV DNA 上兩次檢測都是Not Detected，從未吃過抗乙肝病毒藥。這是乙肝自愈了卻留下了肝硬化和肝鐵沉積嗎？

分別在18年11月和21年六月：

Hepatitis B Virus, Quantitative

[IU]/mL

Value

<10

 

HBV DNA Not Detected

 

17年12月（我理解是檢測到了，但小於10）：

HBV AS IU/mL

IU/mL

Value

<10

 

HBV DNA detected

 

15年12月也檢測到了，但數值低於下限。檢測報告有個特別的注釋：

Hepatitis B Virus DNA

Normal value: <20 IU/mL

(NOTE) *Detected below the Limit of Quantitation (NOTE) *Detected below the Limit of Quantitation *Please note: This patient had HBV viral DNA that was detectable, but was below the Lower Limit of Quantitation of the test (<20 IU/mL). This happens on rare occasions, and is due to the presence of very low concentrations of virus that can not be precisely quantified. The results in these cases are reported as "<20 IU/mL, Detected". The clinical significance of HBV viral DNA detected at this low level is not yet known. These results should be correlated with other clinical or diagnostic findings and re-testing is available upon request for confirmation.
