Subtitle: Detection of HSV Antibodies in Blood Description: The HSV 1 & 2 - IgG test detects antibodies to herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) in the blood. It helps identify past exposure to the viruses and differentiate between HSV-1 and HSV-2 infections. The test does not distinguish between current and past infections but provides valuable information about an individual's immune response to the viruses.
The HSV 1 & 2 IgG test is a blood test used to detect antibodies for Herpes Simplex Virus types 1 and 2. These antibodies indicate a past infection with the virus. The presence of IgG antibodies means that the person has been exposed to the virus at some point in their life. HSV 1 (Herpes Simplex Virus Type 1): Commonly causes cold sores or fever blisters around the mouth. HSV 2 (Herpes Simplex Virus Type 2): Primarily causes genital herpes.

How our test process works!
The HSV (Herpes Simplex Virus) 1 & 2 IgG test is a blood test used to detect the presence of IgG antibodies to HSV-1 and HSV-2, which are the two types of herpes simplex viruses. HSV-1 is commonly associated with oral herpes, while HSV-2 is typically linked to genital herpes.
Purpose of the Test:
Diagnosis: The test helps in diagnosing a past or current HSV infection.
Distinguishing between HSV Types: It differentiates between HSV-1 and HSV-2 infections.
Risk Assessment: It assesses the risk of transmitting the virus to others, especially in sexual relationships or during pregnancy.
Screening: The test can be used as a screening tool in asymptomatic individuals, especially those with potential exposure risks.
Positive IgG: Indicates a past or current infection. The person has been exposed to the virus at some point.
HSV-1 Positive: Higher risk of oral herpes.
HSV-2 Positive: Higher risk of genital herpes.
Negative IgG: Suggests no previous exposure to the virus or a recent infection that hasn't yet produced detectable levels of antibodies.
Seroconversion: In newly infected individuals, it takes time for IgG antibodies to develop, which could mean a negative result in the early stages of infection.
Normal Range
Negative (No IgG Antibodies Detected): No previous exposure to HSV-1 or HSV-2, or very recent infection.
Positive (IgG Antibodies Detected):Past or current infection with HSV-1 or HSV-2.
The test results are usually reported as:
Negative: Below the reference range (e.g., <0.9)
Equivocal: Borderline results (e.g., 0.9–1.1)
Positive: Above the reference range (e.g., >1.1)
Interpretation:
- Negative IgG: No prior exposure to HSV; however, recent infection cannot be ruled out (may require IgM testing or follow-up IgG).
- Positive HSV-1 IgG: Prior exposure to HSV-1 (likely oral herpes).
- Positive HSV-2 IgG: Prior exposure to HSV-2 (likely genital herpes).
- Both Positive: Exposure to both HSV-1 and HSV-2.
- Note: A positive IgG result indicates exposure, not necessarily an active infection. Symptoms and clinical history must guide further evaluation.
Blood Sample: A venous blood sample is typically drawn from a vein in the arm.
