新冠病毒抗體檢測

確定您是否己被新冠病毒感染，或對新冠病毒產生了免疫反應

Semi-quantitative SARS-CoV-2 (COVID-19) IgG Antibody Serology Test

Confirm Immune Response to SARS-CoV-2

高度準確

靈敏度 (Sensitivity): 99.9%

特異性(Specificity): 99.9%

確認自己是否曾受感染，或對新冠肺炎病毒產生了免疫反應

  • 本抗體檢測針對血液中的新冠肺炎抗體（SARS-CoV-2/COVID-19 IgG antibodies）

  • 陽性檢測結果意味著人體已對SARS-CoV-2新冠病毒產生了免疫反應

  • 抗體是人體應對感染所產生的蛋白質。即使在感染期間沒有症狀，也可以產生抗體。

    檢測效益

  • 確認自己對新冠病毒己產生了免疫反應

  • 有抗體的您，己產生了免疫反應，不需要花費時間和金錢重複新冠肺炎病毒核酸檢測

  • 大多數醫學專家認為，抗體可以讓患者對新冠肺炎 (COVID-19)得到短期的免疫能力 (1-3)。但我們不知道這種免疫力能持續多久

  • 本檢測高度準確，特異性為99.9％，大大減少假陽性報告（假陽性意思是您沒有抗體，但檢測錯誤地報告您有抗體）

  • 由於人體對這種病毒的免疫反應尚不清楚，檢測結果不能用於確定免疫水平

  • 檢測申請經由Rainbow醫學總監批准。檢測結果絕對保密。

    誰應該考慮接受此測試

  • 前線醫護人員，公共汽車/出租車司機，零售人員，警察以及經常與公眾接觸的人，長者，及想知道自己是否已經有新冠病毒抗體的人。

  • 患者可以到我們的合作診所抽血

  • 樣品送到全球最大的診斷實驗室之一，Quest Diagnostics 完成測試

  • 檢測時間約為14到18天。

  • 提供 Quest Diagnostics 英文原文檢測報告，和中文檢測結果解釋

  • 本抗體檢測不是一項病毒檢測

  • 如果您現在有新冠肺炎症狀，請立即進行病毒核酸檢測以確認您當前的感染情況

關於此抗體檢測的信息和免責聲明

  • 檢測靈敏度為> 99.9％ (症狀發作後至少15天收集的樣本的估計) (5)

  • 通過NPA4的交叉反應研究評估，估計的檢測特異性約為99.9％(5)

  • 檢測結果以報告指數 ≥1.00為陽性(5)。這個陽性的結果意味著一個人已經對SARS-CoV-2病毒產生了免疫反應。

  • 由於對這種病毒的人體免疫反應尚不清楚，因此檢測結果不能用於指示免疫水平或排除再次感染的機會(5)。

  • 報告指數5小於1.00為陰性，這意味著患者血清樣本中沒有SARS-CoV-2病毒IgG抗體，或者患者樣本中抗體的相對水平低於指數臨界值(5, 7)。

  • 注意：報告指數不應用於量度對SARS-CoV-2感染或再感染的免疫力的持久性。對SARS-CoV-2的免疫力的持久性和持續時間仍未明確定義，並且仍然是全世界科學與公共衛生研究的領域(8)。

  • 本SARSCoV-2 IgG檢測不應用來診斷急性SARS-CoV-2感染。

  • 本SARSCoV-2 IgG檢測僅限於經過1988年臨床實驗室改進修正案 CLIA，42 U.S.C 263a 認證的實驗室，以進行中度或高度複雜性檢測。

SARS-CoV-2 Serology (COVID-19) Antibody (IgG), Immunoassay

  • Presence of IgG antibodies may indicate an immune response to SARS-CoV-2.

  • A positive result may suggest an immune response to a primary infection with SARS-CoV-2, but the relationship between IgG positivity and immunity to SARS-CoV-2 has not yet been firmly established.

  • Antibody tests should not be used to definitively diagnose or exclude SARS-CoV-2 infection.

  • Positive results could also be due to past or present infection with non-SARS-CoV-2 coronavirus strains, such as coronavirus HKU1, NL63, OC43, or 229E.

  • Diagnosis of COVID-19 is made by detection of SARS-CoV-2 RNA by molecular testing methods, consistent with a patient's clinical findings.

  • SARS-CoV-2 IgG antibody assays offered by Quest Diagnostics have been authorized through the U.S. FDA EUA (Emergency Use Authorization) process.

  • Sensitivity: 99.9%

  • Specificity: 99.9%

Test Information and Disclaimer

  • Estimated assay sensitivity is >99.9% for specimens collected at least 15 days post-symptom onset(5)

  • Estimated assay specificity is approximately 99.9% based on NPA4 assessed by performing cross-reactivity studies(5)

  • Test result is reported as positive at an index of ≥1.00 (5). This positive result means that an individual has developed an immune response to SARS-CoV-2.

  • Since much is still not known about the body’s immune response to this virus, this test result cannot be used to indicate a level of immunity or rule out the chance for reinfection. (5)

  • Negative result is reported at an index of <1.00 (5), which means that the patient serum specimen had no SARS-CoV-2 spike IgG antibodies, or that the relative level of antibodies in the patient specimen was below the index cutoff.(5, 7)

  • Note: this index value should not be interpreted as a measurement of durable immunity or protection from SARS-CoV-2 infection or reinfection. Durability and duration of immunity to SARS-CoV-2 is still not clearly defined and continues to be an area of national and global scientific and public health research.(8)

  • The SARSCoV-2 IgG assay should not be used to diagnose acute SARS-CoV-2 infection.

  • Testing is limited to laboratories certified under the Clinical Laboratory Improvement Amendments (CLIA) of 1988, 42 U.S.C 263a, to perform moderate or high complexity test.
