If the Endomysial Antibody Screen (IgA) is positive, 

2. Endomysial Antibody Titer will be performed at an additional charge (CPT code(s): 86256).

If the Total IgA is less than the lower limit of the reference range, based on age, 

3. Tissue Transglutaminase IgG will be performed at an additional charge (CPT code(s): 83516).

Clinical Significance

Celiac disease is caused by an immune response to gluten in genetically sensitive individuals. The diagnosis is largely based on a biopsy of the small intestine, but serologic tests also help support a diagnosis and may assist identification of patients who may require biopsy.

Tissue transglutaminase antibodies (tTG, IgA) is a marker with 95% sensitivity and specificity. Total IgA is measured because 2-3% of celiac disease patients are IgA deficient. Because tTG, IgA, and anti-Gliadin IgA tend to decrease in patients on a gluten-free diet, these markers are also used to assess dietary compliance.

The endomysial antibody (EMA, IgA) assay has high specificity for celiac disease and is used to confirm positive anti-tTG results.

ABO Group and Rh Type

Blood typing is used to determine an individual's blood group, to establish whether a person is blood group A, B, AB, or O and whether he or she is Rh positive or Rh negative.

The Different Blood Types

There are four major blood groups and eight different blood types. Doctors call this the ABO Blood Group System.

The groups are based on whether or not you have two specific antigens -- A and B:

• Group A has the A antigen and B antibody.
• Group B has the B antigen and the A antibody.
• Group AB has A and B antigens but neither A nor B antibodies.
• Group O doesn’t have A or B antigens but has both A and B antibodies.

There’s also a third kind of antigen called the Rh factor. You either have this antigen (meaning your blood type is “Rh+” or “positive”), or you don’t (meaning your blood type is “Rh-” or “negative”). So, from the four blood groups, there are eight blood types:

• A positive or A negative
• B positive or B negative
• AB positive or AB negative
• O positive or O negative

A Complete Blood Count (CBC) Panel is used as a screening test for various disease states including anemia, leukemia and inflammatory processes.

A CBC blood test includes the following biomarkers: WBC, RBC, Hemoglobin, Hematocrit, MCV, MCH, MCHC, RDW, Platelet count, Neutrophils, Lymphs, Monocytes, Eos, Basos, Neutrophils (Absolute), Lymphs (Absolute), Monocytes(Absolute), Eos (Absolute), Basos (Absolute), Immature Granulocytes, Immature Grans (Abs)

Useful in the diagnosis of hypochromic, microcytic anemias. Decreased in iron deficiency anemia and increased in iron overload.

A Hemoglobin (Hb) A1c Blood Test evaluates the average amount of glucose in the blood. The A1c test will help determine whether you are at a higher risk of developing diabetes; to help diagnose diabetes and prediabetes; to monitor diabetes and to aid in treatment decisions.

To assist with control of blood glucose levels, the American Diabetes Association (ADA) has recommended glycated hemoglobin testing (HbA1c) twice a year for patients with stable glycemia, and quarterly for patients with poor glucose control. Interpretative ranges are based on ADA guidelines.

Lactate Dehydrogenase (LD) (LDH)

Elevations in serum lactate dehydrogenase occur from myocardial infarction, liver disease, pernicious and megaloblastic anemia, pulmonary emboli, malignancies, and muscular dystrophy

Lipid Panel includes: Total Cholesterol, HDL Cholesterol, Triglycerides, LDL-Cholesterol (calculated), Cholesterol/HDL Ratio (calculated), Non-HDL Cholesterol (calculated)Total cholesterol —this test measures all of the cholesterol in all the lipoprotein particles.High-density lipoprotein cholesterol (HDL-C) — measures the cholesterol in HDL particles; often called "good cholesterol" because it removes excess cholesterol and carries it to the liver for removal.Direct LDL - Low-density lipoprotein cholesterol (LDL-C) — calculates the cholesterol in LDL particles; often called "bad cholesterol" because it deposits excess cholesterol in walls of blood vessels, which can contribute to atherosclerosis. Usually, the amount of LDL cholesterol (LDL-C) is calculated using the results of total cholesterol, HDL-C, and triglycerides.Triglycerides — measures all the triglycerides in all the lipoprotein particles; most is in the very low-density lipoproteins (VLDL).

Measles Antibody IgG - to establish whether you have immunity to measles due to a previous infection or to vaccination.

Measles, also known as rubeola, causes fever, irritability, respiratory illness, and the characteristic skin rash. Immunization has greatly diminished the incidence of measles. The presence of IgG is consistent with immunity or prior exposure. 

Alternate Test Name: Measles Immunity Test

Measles Immunity Test - to establish whether you have immunity to measles due to a previous infection or to vaccination.

Measles, also known as rubeola, causes fever, irritability, respiratory illness, and the characteristic skin rash. Immunization has greatly diminished the incidence of measles. The presence of IgG is consistent with immunity or prior exposure. 

Alternate Test Name: Measles Antibody IgG

For diagnosis of hypothyroidism and hyperthyroidism.

Note: Free T4 Index (T7) will only be calculated and reported if test code code 861 (T3 Uptake) is ordered as well.

This test is useful in the differential diagnosis of male hypogonadism. For males 18 years of age and older only. Pediatric and Female patients will need to order Testosterone, Total, MS #15983.

Please note: If Testosterone, Total, Males (Adult) Only #873 is ordered for a pediatric or female patient, the lab will automatically change the test to and charge for Testosterone, Total, MS #15983.

The Thyroid-stimulating Hormone (TSH) Blood Test is for differential diagnosis of primary, secondary, and tertiary hypothyroidism. The TSH test is also useful in screening for hyperthyroidism. This assay allows adjustment of exogenous thyroxine dosage in hypothyroid patients and in patients on suppressive thyroxine therapy for thyroid neoplasia.

Dipstick urinalysis is important in accessing the chemical constituents in the urine and the relationship to various disease states. Microscopic examination helps to detect the presence of cells and other formed elements.

Vitamin B12 is decreased in pernicious anemia, total or partial gastrectomy, malabsorption and certain congenital and biochemical disorders

COVID-19 Antibody (IgG), Immunoassay

IMPORTANT - Test collection is available only to patients who: are asymptomatic; have been asymptomatic for at least 10 days; lack a fever (as assessed by non-contact thermometer checks at time of visit); and are wearing a face mask.

THIS IS NOT A TEST FOR AN ACTIVE INFECTION

Patients suspected of having or confirmed to have active COVID-19 infection or disease may not visit Quest patient service centers, which are not equipped to collect the necessary respiratory specimens for molecular COVID-19 diagnostic testing. Patients who believe they may have COVID-19 are strongly encouraged to contact their healthcare provider.

"This test checks for a type of antibody called immunoglobulin G (IgG) that is the result of past or recent exposure to COVID-19, also known as the novel coronavirus. The human body produces IgG antibodies as part of the immune response to the virus. It usually takes around 10 to 18 days to produce enough antibodies to be detected in the blood.

Test results may help identify if you were previously exposed to the virus and, if exposed, can check whether or not your body has produced antibodies. Antibodies typically suggest protective immunity after you’ve recovered or been exposed to COVID-19. However, evidence is still being collected to determine if IgG antibodies provide protective immunity against SARS-CoV-2, the virus that causes COVID-19 infection.

If you were never diagnosed with COVID-19, this test can help determine if you may have been previously exposed to the virus.

If you were diagnosed with COVID-19, this test can check whether or not your body has produced antibodies.

Multiple sources, including the CDC and healthcare experts, recommend you discuss your test results and whether to return to work with your healthcare provider and employer.

PATIENT SERVICE CENTERS - COVID-19 Antibody (IgG) testing requirements.

1. A FACE MASK IS REQUIRED

2. AN APPOINTMENT IS REQUIRED - For the safety of patients and employees, Quest has limited appointment times for COVID-19 Antibody (IgG) testing.

This test may be helpful if you: 

• Have had a positive test for COVID-19 and it has been at least 7 days and you want to know if you have detectable levels of IgG antibodies
• Have not experienced a fever or felt feverish in the last 3 days
• Have not experienced new or worsening symptoms of COVID-19 in the past 10 days: loss of smell or taste, shortness of breath or difficulty breathing, feeling weak or lethargic, lightheadedness or dizziness, vomiting or diarrhea, slurred speech, and/or seizures

This test may NOT be helpful if you are: 

• Feeling sick or have had a fever within the last 3 full days, please contact a healthcare provider
• Trying to diagnose COVID-19, please contact a healthcare provider
• Less than 7 days since being tested for and diagnosed with COVID-19
• Directly exposed to COVID-19 in the past 14 days
• A person with a compromised immune system, a condition that makes it difficult to fight infections
• For the latest information on COVID-19, please visit our website for information for patients.

What will my results tell me? - Your test results may help identify if you were exposed to the virus and, if so, whether or not your body has these antibodies. Although having antibodies usually gives immunity from further infection, there is not enough evidence at this time to suggest that people who have IgG antibodies are protected against future SARS-CoV-2 infections. ?Results from this test also will not provide any information on whether you can spread the virus to others. 

If you have questions about returning to work, contact your employer for guidance. Be sure to continue to follow federal, state, and local government guidance regarding social distancing and isolation. 

Are there any limitations to IgG antibody tests? - It usually takes around 10 to 18 days after being infected with SARS-CoV-2 for your body to produce enough antibodies for detection in the blood. Getting an IgG antibody test too soon after being infected may cause a negative result that is false (false negative). Additionally, IgG antibody tests may detect IgG antibodies from previous exposure to coronaviruses other than SARS-CoV-2. This can cause a positive result that is false (false positive). There is not enough evidence at this time to suggest that people who have IgG antibodies are protected against future SARS-CoV-2 infections. 

Are there any risks involved in getting this test? - There is no risk involved in getting this test. The test is conducted by collecting a blood sample. 

How do I prepare for the test? - To have your specimen collected at the patient service center, you will need to wear a face mask, consent to a non-contact thermometer checks at the time of visit, and depending upon the patient service center schedule an appointment. There is no other special preparation other than the requirements to receive this test that is restricted to only to patients who: are asymptomatic; have been asymptomatic for at least 10 days; lack a fever (as assessed by non-contact thermometer checks at time of visit); and are wearing a face mask.

What is coronavirus disease (COVID-19)? 
Coronavirus disease (also called COVID-19) is a serious respiratory illness. It is caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus), one of the most recently discovered types of coronaviruses. It was first identified in Wuhan, China, at the end of 2019 and has spread globally, becoming a worldwide pandemic. Those who have this disease may or may not experience symptoms, which range from mild to severe. 

What is a serology test? 
This serology? ?test checks for a type of antibody called ?immunoglobulin G (IgG)?. If you’ve been exposed to the SARS-CoV-2 virus, your body produces IgG antibodies as part of the immune response to the virus. This test cannot tell you if you have an active infection with SARS-CoV-2. If you suspect you have COVID-19, follow up with your healthcare provider about getting a molecular (PCR) test. 

Note: This test can sometimes detect antibodies from other coronaviruses, which can cause a false positive result if you have been previously diagnosed with or exposed to other types of coronaviruses. Additionally, if you test too soon, your body may not have produced enough IgG antibodies to be detected by the test yet, which can lead to a false negative result. 

At this time, antibody testing is mainly used in studies to determine how much of the population has been exposed to COVID-19. There is not enough evidence at this time to suggest that people who have IgG antibodies are protected against future COVID-19 infection. Positive or negative antibody tests do not rule out the possibility of COVID-19 infection. Results also do not provide any information on whether you can spread the virus to others.

Blood typing is used to determine an individual's blood group, to establish whether a person is blood group A, B, AB, or O and whether he or she is Rh positive or Rh negative.

The Different Blood Types

There are four major blood groups and eight different blood types. Doctors call this the ABO Blood Group System.

The groups are based on whether or not you have two specific antigens -- A and B:

• Group A has the A antigen and B antibody.
• Group B has the B antigen and the A antibody.
• Group AB has A and B antigens but neither A nor B antibodies.
• Group O doesn’t have A or B antigens but has both A and B antibodies.

There’s also a third kind of antigen called the Rh factor. You either have this antigen (meaning your blood type is “Rh+” or “positive”), or you don’t (meaning your blood type is “Rh-” or “negative”). So, from the four blood groups, there are eight blood types:

• A positive or A negative
• B positive or B negative
• AB positive or AB negative
• O positive or O negative

Vitamin B12 is decreased in pernicious anemia, total or partial gastrectomy, malabsorption and certain congenital and biochemical disorders

Measurement of serum 25-OH vitamin D concentrations provide a good index of circulating vitamin D activity in patients not suffering from renal disease. Lower than normal 25-OH vitamin D levels can result from a dietary deficiency, poor absorption of the vitamin or impaired metabolism of the sterol in the liver. A 25-OH vitamin D deficiency can lead to bone diseases such as rickets and osteomalacia. Above normal levels can lead hypercalcemia.
