结果医生听说是travel用的直接开了 total antibody 的测试，这个只测对nuclecapsid的抗体，结论是阴性
ARS-COV-2 TOTAL AB
| Result obtained by Roche cobas ECLIA. | ||
| Kit approved by Health Canada. | ||
| This assay detects total antibodies to the | ||
| SARS-CoV-2 Nucleocapsid protein, | ||
| which can only be present from a | ||
| natural COVID-19 infection but not after vaccination. | ||
| In principle, this assay can detect high affinity antibodies | ||
| of all isotypes (i.e., IgG, IgA, IgM), but it | ||
| preferentially detects IgG antibodies. |
然后我又找医生重新开单检测了，panel test包括对两种蛋白的检测，一个是
SARS-CoV2 NPROT TOTAL AB 还是阴性
| This test detects total antibodies to the SARS-CoV-2 | ||
| Nucleocapsid protein which can develop through natural | ||
| exposure but not vaccination. The absence of antibodies | ||
| does not rule out current or previous infection. Negative | ||
| results may occur if specimen is collected too soon | ||
| following infection or from immunocompromised patients. | ||
| SARS-CoV-2 antibody tests should NOT be used to infer | ||
| immunity status or infectivity. If there is a high clinical | ||
| suspicion of infection, consider recollecting in 2-3 weeks. | ||
| If the patient is symptomatic, consider molecular COVID-19 | ||
| testing. Result obtained by Roche cobas ECLIA. Kit approved | ||
| by Health Canada. This assay can detect high affinity | ||
| antibodies of all isotypes (i.e., IgG, IgA, IgM) but | ||
| preferentially detects IgG antibodies |
SPIKE QUANT TOTAL ANTIBODY 这个我的浓度是>2500U/ML
| REPEATED | ||
| This test detects total antibodies to the SARS-CoV-2 Spike | ||
| protein which can develop through natural exposure and/or | ||
| vaccination but cannot differentiate between them. It is | ||
| yet to be determined what level of antibody to SARS-CoV-2 | ||
| spike protein correlates to immunity against COVID-19. | ||
| Results obtained by Roche cobas ECLIA. Kit approved by | ||
| Health Canada. This assay in principle can detect high | ||
| affinity antibodies of all isotypes (IgG, IgA, IgM), but | ||
| preferentially detects IgG antibodies. | ||
| Interpretation: | ||
| Negative < 0.80 U/mL | ||
| Positive > 0.79 U/mL |
两相对比，就是疫苗后形成了抗体。这个抗体也是我travel的目的地所需要的（lgG antibody against spike protein）。这样可以缩短隔离期。
