Introduction
In herpes simplex virus antibody testing, the normal value for IgM antibodies is negative; a positive result indicates a recent infection. A negative IgG antibody result indicates no previous infection, while a positive result suggests a past infection. Some test reports may include numerical values, such as IgM <1.0 COI and IgG <1.0 COI indicating negative results. Specific interpretations should refer to the reference ranges provided by the testing facility.
Under normal circumstances, the normal value for herpes simplex virus testing is negative, with slight variations in numerical standards across different test items. Antibody tests typically consider "negative" or values below a specific threshold as normal. If concerned, it is advisable to seek medical consultation in advance. Detailed analysis is as follows:
In herpes simplex virus antibody testing, a normal IgM antibody value is negative, while a positive result suggests recent infection. A negative IgG antibody result indicates no prior infection, whereas a positive result indicates past infection. Some test reports may provide numerical values—for example, IgM < 1.0 COI and IgG < 1.0 COI are considered negative—but specific reference ranges should follow those provided by the testing facility.
The normal value for viral DNA testing is below the detection limit or undetected, indicating no viral replication or very low viral load in the sample. If the value exceeds the lower limit, it suggests the presence of viral infection, potentially in an active phase, and the clinical symptoms should be considered for further assessment of the condition.
Herpes simplex virus test results should be evaluated comprehensively in combination with symptoms and medical history; conclusions should not be drawn based on a single value alone. If test results are abnormal, timely consultation at a正规 hospital is recommended, with follow-up tests or treatment carried out in accordance with medical advice. Do not interpret reports by oneself.
