Herpes Diagnosis — What to Know
- Lesion PCR for outbreaks: the definitive test during an active sore.
- IgG for past exposure: type-specific serology for asymptomatic screening.
- Clinical picture guides: grouped vesicles and recurrence pattern are diagnostic evidence.
Herpes Diagnosis in Kathmandu
- Lesion PCR ~2–12d — acute diagnostic on a fresh sore.
- Serology ~3–12wk — status — typed antibodies.
- ~50% asymptomatic shedding — transmission discussion.
- Managed not cured — antivirals control it.
Herpes Diagnosis — the Two Methods by the Question
Herpes is diagnosed by two methods matched to question: lesion PCR for a fresh sore (the ~2–12 day acute diagnostic — ~95% sensitive on fresh lesion) and typed serology for status question (the ~3–12 week window — type-specific antibodies for HSV-1 vs HSV-2).
The method is matched to presentation: a fresh sore is lesion-PCR case ( direct detection on shedding virus); a status question or an exposure-history is serology case ( antibodies detected where no lesion is present).
The honest framing: windows are biological — lesion PCR on a healing lesion is reduced sensitivity ( false-negative risk); serology too early is inconclusive — correct test at correct timing is reliable version.
Herpes diagnosis uses the correct method for the clinical situation — lesion PCR for active outbreaks (the definitive test), type-specific IgG serology for past exposure or asymptomatic screening. The diagnosis is not just the test; it is the test plus the clinical picture (grouped vesicles, recurrence pattern, prodrome) that determines the diagnosis.
The Lesion PCR — the Acute Diagnostic
The lesion PCR detects virus directly on a fresh sore or an early blister — ~95% sensitive within the ~2–12 day window — acute diagnostic where a lesion is present. The fresh lesion is diagnostic opportunity; a healing lesion is reduced sensitivity ( false-negative risk).
The result reports HSV-1 vs HSV-2 — type determined — type informing prognosis (the HSV-2 is genital-associated; the HSV-1 is oral-associated but genital HSV-1 is increasingly common).
Lesion PCR ~95%
The acute diagnostic — ~2–12 day window.
Fresh Lesion the Window
The shedding virus is test.
Healing = Reduced
A healing lesion is false-negative risk.
Typed Result
HSV-1 vs HSV-2 — prognosis informed.
The Typed Serology — the Status
The typed serology detects type-specific antibodies for HSV-1 vs HSV-2 — status question ( prior exposure, standing infection) — the ~3–12 week window for antibodies to develop.
The serology is for where no lesion is present — status question — typed result distinguishing the HSV-1 ( oral-associated, increasingly-common genital) from the HSV-2 ( genital-associated) for prognosis and counselling.
Type-Specific Antibodies
HSV-1 vs HSV-2 distinguished.
~3–12 Week Window
The antibodies take interval — biological constraint.
For the Status
Where no lesion is present — standing-infection question.
Typed for the Prognosis
The type informing recurrence and transmission.
The Windows — Matched to the Question
The lesion PCR window is ~2–12 days — acute period where sore is shedding virus — method for where a fresh lesion is present. A healing lesion or a resolved one is serology question instead.
The serology window is ~3–12 weeks — antibodies take that long to develop — method for status question where no lesion is present, timed to the ~3–12 week point for reliable detection.
Lesion ~2–12d
The acute window — fresh sore is test.
Serology ~3–12wk
The status window — antibodies develop.
Matched to the Presentation
The correct method for question.
Wrong Timing = Inconclusive
The honest window framing.
The Interpretation — the Chronic-Infection Context
A positive is interpreted in chronic-infection context: herpes is managed not cured — antivirals (episodic or suppressive) control it — transmission discussion (the ~50% asymptomatic shedding — transmission possible without visible lesions), and not-infidelity honesty (a positive can be a long-standing infection, not a recent acquisition).
A negative is read against timing — a too-early serology is inconclusive; a negative-lesion-PCR is acute-not-detected ( timing, healing-lesion possibility) — interpretation matching method.
Managed Not Cured
The antivirals control it.
~50% Asymptomatic Shedding
The transmission possible without visible lesions.
Not-Infidelity Honest
A positive can be prior, not recent.
Timing-Aware Negative
The honest read against method.
Herpes Diagnosis
Lesion PCR
Swab of a fresh sore — detects HSV DNA directly, the definitive outbreak test.
Type-specific IgG
Blood test for past exposure — HSV-1 and HSV-2 separately.
Clinical picture
Grouped vesicles, recurrence pattern, prodrome — the symptoms that guide testing.
Typing matters
HSV-1 vs HSV-2 changes prognosis — type-specific testing guides counseling.
