It's also unclear what level of antibody level indicates a high level of protection. Segev has published a number of papers on this population, including a study in the Annals of Internal Medicine of 30 transplant patients who received third doses of COVID vaccines, and has correlated neutralization assays with commercial antibody test readouts. More research also is needed to know how much past infection with the virus helps protect you from getting another infection. But Watzl is optimistic, emphasizing that "more is better. Other than that, I've been very healthy and not susceptible to sicknesses, and as a result, I don't bother with flu shots, nor did I get the Covid shot. Too much may not always fetch good outcome.

An important point to remember is that most commercially available tests -- delivered at the point of care in a clinician's office or performed in a hospital lab -- aren't neutralizing assays, said Clayton Wilburn, MD, of the College of American Pathologists' Clinical Chemistry Committee. "The real answer is, we just don't know" that threshold, Nathaniel (Ned) Landau, PhD, a virologist in the department of microbiology at NYU Grossman School of Medicine, told MedPage Today.

These new data show that, when patient samples were analyzed with the semi-quantitative assay that Labcorp is running, higher levels of antibodies correlated with higher levels of neutralizing antibodies, which, in turn, have been correlated with increased protection from infection, reinfection and severe disease .1,2. "We're trying to learn if they've had natural infection.". It's the 21st Century come on already. "Immunity passports" in the context of COVID-19. I was tested yesterday with the quantitative antibodies test against SARS Covid 19 and my numbers are 16 for the Spike antibodies. ", Segev said he and his team do see some clear trends in the LabCorp data. Low antibody levels can be due to age or a suppressed immune system. Pfizer and the lab where i was tested use the same test: Abbott SARS-CoV-2 IgG II Quant test, Dear Claudia Chamberlain Commercial tests typically look for either spike or nucleocapsid antibodies. Understanding how long antibody levels remain high enough to prevent infection is important in understanding, absent vaccination, whether children may be vulnerable to COVID-19 and in modeling how COVID-19 spreads .

Antibody tests are not used if you have symptoms of COVID-19 or for diagnosing a current case of COVID-19. We report that a relatively low antibody titer [the concentration of antibodies in the blood] is needed for protection., Another article, this one on the Childrens Hospital of Philadelphia website, agrees with Barouchs assessment. Studies are ongoing to learn more about COVID-19 antibodies as well as other parts of the immune system. The report also provides a numeric value, but only in a generic "units/mL. In one cluster of COVID-19 patients from China, most people produced high levels of neutralizing antibodies that prevent the virus from infecting new cells, according to a preliminary report .

My test results caution that it is yet undetermined what level of antibody to SARS-CoV-2 spike protection correlates to immunity against developing symptomatic SARS-CoV-2 disease.
