COVID-19 RT-PCR & Antibody Testing Now Available
Fast and accurate testing determines the presence of the SARS-CoV-2 virus.
NEW! IGeneX is now offering a COVID-19 + FLU + RSV Combo Test. Test for all three illnesses with one swab. Contact us below to get started.
IMPORTANT: With the exception of Airline Travel 24-Hour and Same-Day Testing, IGeneX does not sell COVID-19 tests directly to patients. Patients must order a test through an authorized healthcare provider. Healthcare providers can contact IGeneX at 1-800-832-3200 to be set up in our COVID-19 Provider Program.
NEW! IGeneX is now offering the COV5T SARS-CoV-2 Vaccine Response Panel, which tests for antibody response. This comprehensive test panel gives patients the ability to monitor their overall response to the vaccine. The panel consists of two SARS-CoV-2 ImmunoBlot tests (one for IgM, one for IgG). ImmunoBlots measure antibody response from activation of B cells.
DESCRIPTION OF COVID-19 TESTS

Price: $135
CPT Code: U0003
The C100 SARS-CoV-2 Real-Time RT PCR test detects the presence of the underlying virus that causes COVID-19 and is for use with patients who meet current guidance for evaluation of infection. Many COVID-19 patients are asymptomatic, so testing those patients must also be considered.
Limit of Detection (LOD): 1000 (cp/mL)
Test Interpretations
• A positive result is considered definitive evidence of infection
• If no viral sequence is present, amplification will not occur, resulting in a negative result
A negative result means that no SARS-Cov-2 RNA was detected in the sample because it was either absent or below the limit of detection. Therefore, test results need to be considered in the context of patient symptoms and exposure history.

The C400 ImmunoBlot IgG test can determine if a patient’s immune system has produced IgG antibodies against the SARS-CoV-2 infection. IgG antibodies typically start developing 10 days from the onset of symptoms, and suggest that the patient may be in the recovery phase.
Sensitivity: Based on a study performed on 65 samples from 33 patients, between 0- 54 days after Real time RT-PCR was positive for SARS-CoV-2, 81.8% had SARS-CoV-2 specific IgG antibodies.
Specificity: 98.2% (n=221)
Test Interpretations for IgG Antibodies
• A sample is considered positive if two of the following bands are present: 75 kDa or 58 kDa, 50 kDa, and 25 kDa
• A sample is considered indeterminate if one of the following bands is present: 75 kDa, 58 kDa, and 25 kDa
• Negative: No SARS-CoV-2 specific IgG antibodies detected.
**Cross-reactivity to the other coronaviruses has not been tested. This test is under FDA review.

The COV1 ImmunoBlot Panel 1 test detects IgM and IgG antibodies against the infection. The body makes IgM antibodies when first infected with a new virus, usually after seven days. IgG antibodies typically start developing 10 days from the onset of symptoms, and suggest that the patient may be in the recovery phase.
Sensitivity: Based on a study performed on 65 samples from 33 patients, between 0- 54 days after positive by Real time RT-PCR for SARS-CoV-2, 93.9% had antibodies to SARS-CoV-2. 72.7% had IgM antibodies and 81.8% had IgG antibodies.
Specificity: IgM: 99.1%; IgG: 98.2% (n=221)
Test Interpretations for IgG Antibodies
• A sample is considered positive if two of the following bands are present: 75 kDa or 58 kDa, 50 kDa, and 25 kDa
• A sample is considered indeterminate if one of the following bands is present: 75 kDa, 58 kDa, and 25 kDa
• Negative: No SARS-CoV-2 specific IgG antibodies detected.
Test Interpretations for IgM Antibodies
• A sample is considered positive if two of the following bands are present: 75 kDa, 58 kDa, 50 kDa and 25 kDa
• A sample is considered indeterminate if one of the following bands is present: 75 kDa, 58 kDa, 50 kDa, and 25 kDa
• Negative: No SARS-CoV-2 specific IgM antibodies detected.
**Cross-reactivity to the other coronaviruses has not been tested. This test is under FDA review.

The COV2 SARS-CoV-2 Complete Panel 2 includes C100 and COV1. This test panel is the recommended option because it provides the most comprehensive view of exposure to COVID-19 by testing for both active infection and antibody response. It helps determine if someone could potentially spread the virus, as well as determine if that person is immune from further infection.

IGeneX is now offering the COV5T SARS-CoV-2 Vaccine Response Panel, which tests for antibody response. This comprehensive test panel gives patients the ability to monitor their overall response to the vaccine. The panel consists of two SARS-CoV-2 ImmunoBlot tests (one for IgM, one for IgG). ImmunoBlots measure antibody response from activation of B cells.
IGENEX RECOMMENDS TESTING WITH A PANEL
IGeneX recommends testing for both active infection and antibody response due to overlapping periods of active infection, initial IgM antibody response, and antibody conversion from IgM to IgG. The chart below illustrates the overlap. Without testing for both, some patients will be missed.
1. The virus is detectable by RT-PCR at the onset of symptoms for up to 3 weeks (solid blue line)
2. The virus can be isolated up to 1 week after the onset of symptoms (solid red line).
3. By week 2, IgM antibodies were detectable in serum and remained detectable nearly one month after symptoms first appeared (gray dashed line)
4. Week 3 onward, IgG antibodies are detected (orange dashed line)
5. Between week 3 and week 6, some patients have both IgM and IgG antibodies (blue dotted line)
WHY AN IMMUNOBLOT IS A SUPERIOR COVID-19 ANTIBODY TEST
In an ImmunoBlot, SARS-CoV-2 antigens are sprayed onto a nitrocellulose membrane. If specific antibodies to SARS-CoV-2 antigens are present, they will bind to the corresponding antigen bands. A dark purple precipitate will develop on the antigen-antibody complexes. Based on the studies to date, the ImmunoBlots have superior specificity and sensitivity compared to ELISA and Lateral Flow assays.
Sensitivity
– Antigens are individually present on the blot
– Poor sensitivity, especially when antibody levels are low (early disease for IgM; late disease for IgG)
– A single antigen is mostly used
Specificity
– Specific and pure recombinant antigens are used
Stage of Disease
– Active (IgM and IgG)
– Late (IgG)
HOW COVID-19 TESTING WORKS?
Contact Your Doctor
You and your Healthcare Provider will discuss symptoms, order the appropriate test(s), and fill out the IGeneX COVID-19 Test Requisition Form.
Collect & Ship Sample
A Sample is collected and sent to IGeneX as described in the test requisition form and in accordance with CDC specimen collection and shipping guidelines.
Test is Performed
IGeneX conducts the test based on the product that was ordered. The test will be a PCR test conducted on a nasopharyngeal swab, or an ImmunoBlot test conducted using a blood sample.
Results are Provided
Results will be provided to the patient and physician within 24-48 hours for PCR testing, and within 3-5 business days for ImmunoBlots. Positive results will also be reported to the County and State Health Departments.
WHY IGENEX FOR COVID-19 TESTING?
Dr. Jyotsna Shah, President and Laboratory Director at IGeneX.
At IGeneX, we are real people who understand the very personal, real-life impact that COVID-19 is having, and we are pleased to be one of the few CLIA certified labs that offer both PCR and antibody tests for COVID-19. It is our goal to help people get back to living a normal life quickly, but do so in a way that will be safe for them and family at home.
We encourage everyone to talk to their doctor and consider being tested. This includes asymptomatic individuals who think they are okay, but may be unknowingly putting others at risk.
For more information on COVID-19 or our testing products like a COVID-19 antibody test kit, please contact IGeneX today.
