Hi mga katusok!

May case lang sana akong gustong i-discuss:

Initial test (using RightSign kit):

• Dengue IgM: Positive
• Dengue IgG: Negative
• NS1 Antigen: Negative

Since kine-question yung result, nag-send out ng serum sample. Pero pagbalik ng results, negative lahat (NS1, IgM, IgG)

Any insights kung ano possible reason behind this discrepancy? Expiry naman ng kit is 2027 so okay pa. Possible kaya false positive IgM? Or may pre-analytical/analytical factors?

Thank you!
