Spike protein antibody testing changed?
-
I have recently joined Leading Edge Clinic believing that I am a victim of spike protein shedding in 2022 and again this year (2024). I was sent to LabCorp (<b style=”font-family: inherit; font-size: inherit; color: var(–bb-body-text-color);”>SARS CoV-2 Antibody Profile, Nucleocapsid and Spike) and test results came back at 7.2.
SARS-CoV-2 Antibody Profile
Test Current Result and Flag Previous Result and Date Units Reference Interval
SARS-CoV-2 Ab, Nucleocapsid
A, 01 Positive Negative
Results suggest recent or prior infection with SARS-CoV-2. Correlation
with epidemiologic risk factors and other clinical and laboratory
findings is recommended. Serologic results should not be used as the
sole basis to diagnose or exclude recent SARS-CoV-2 infection. False
positive results infrequently occur due to prior infection with other
human Coronaviruses.
This assay will not detect antibodies induced by the currently
available SARS-CoV-2 vaccines. The current vaccines elicit
antibodies specific to the viral spike protein. Labcorp offers
two test codes that detect viral spike-specific antibodies:
164090 SARS-CoV-2 Semi-Quantitative Total Antibody, Spike and
164055 SARS-CoV-2 Antibody, IgG, Spike (Qualitative).
Positive results with this SARS-CoV-2 Antibodies, Nucleocapsid
assay suggest recent or previous natural infection with
SARS-CoV-2.
SARS-CoV-2 Semi-Quant Spike
Ab A, 01 7.2 U/mL Negative<0.8
SARS-CoV-2 Spike Ab Interp A, 01 Positive
Antibodies against the SARS-CoV-2 spike protein receptor binding
domain (RBD) were detected. It is yet undetermined what level of
antibody to SARS-CoV-2 spike protein correlates to immunity against
developing symptomatic SARS-CoV-2 disease. Studies are underway to
measure the quantitative levels of specific SARS-CoV-2 antibodies
following vaccination. Such studies will provide valuable insights
into the correlation between protection from vaccination and
antibody levels.
Roche Elecsys Anti-SARS-CoV-2 SI believe that the 7.2 reading correlates to a positive COVID-19 test in early November, 2023. Is there another test that I can take to identify spike protein shedding since I am unvaccinated?
