Analysis (E)

All our Analysis with the initial letter “E”.

EBV (VCA) IgG

The Epstein–Barr virus viral-capsid antigen (EBV-VCA) is the viral protein that forms the viral capsid of the Epstein–Barr virus. It is the antigen targeted by anti-VCA antibodies. Such antibodies can be used in serology to diagnose infectious mononucleosis. Elevated Anti-VCA IgG indicates prior infection.

Specimen: 0.2 ml Serum

Reference Values:

Negative: <0.8
Equivocal: 0.8-1.2
Positive: >1.2

Method: ELISA

Loinc: 5158-1

 

EBV (VCA) IgM

The Epstein–Barr virus viral-capsid antigen (EBV-VCA) is the viral protein that forms the viral capsid of the Epstein–Barr virus. It is the antigen targeted by anti-VCA antibodies. Such antibodies can be used in serology to diagnose infectious mononucleosis. Elevated Anti-VCA IgM indicates acute infection.

Specimen: 0.2 ml Serum

Reference Values:

Negative: <0.8
Equivocal: 0.8-1.2
Positive: >1.2

Method: ELISA

Loinc: 5160-7

 

Echinococcus IgG

Echinococcus is an infection caused by the echinococcus multilocularis worm, which is a parasitic tapeworm. The infection is rare in the United States. It occurs more often in the Middle East, Africa, Central Asia, and the Mediterranean. Echinococcus IgG = Past Infection

Specimen: Serum

Reference Values:

Negative: <8 U/ml
Equivocal: 8-12 U/ml
Positive: >1.0 U/ml

Method: CLIA

Loinc: 22265-3

Specimen: Serum

Reference Values:

Negative: <8 U/ml

Echovirus IgG

Enteric cytopathic human orphan (ECHO) viruses are a group of viruses that lead to gastrointestinal infection and skin rashes. Echovirus IgG = Past Infection

Specimen: Serum

Reference Values: Negative (Positive = Past Infection)

Method: IFA

Loinc: 51840-7

 

Echovirus IgM

Enteric cytopathic human orphan (ECHO) viruses are a group of viruses that lead to gastrointestinal infection and skin rashes. Echovirus IgM = Acute Infection

Specimen: Serum

Reference Values: Negative

Method: IFA

Loinc: 51841-5

 

Endomysial IgA Antibodies

Anti-endomysial antibodies (EMA) are present in celiac disease. They do not cause any direct symptoms to muscles, but detection of EMA is useful in the diagnosis of the disease. Endomysial IgA = Acute Infection

Specimen: Serum

Reference Values: Negative

Method: IFA

Loinc: 27038-9

 

Endomysial IgG Antibodies

Anti-endomysial antibodies (EMA) are present in celiac disease. They do not cause any direct symptoms to muscles, but detection of EMA is useful in the diagnosis of the disease. Endomysial IgG = Past Infection

Specimen: Serum

Reference Values: Negative

Method: IFA

Loinc: 51699-7

 

Erythropoietin (EPO)

Erythropoietin, also known as EPO, is a glycoprotein hormone that controls erythropoiesis, or red blood cell production. It is a cytokine (protein signaling molecule) for erythrocyte (red blood cell) precursors in the bone marrow.

Specimen: 0.2 ml Serum

Reference Values:

Females: 3.7-19.4 mU/ml
Males: 2.6-34.0 mU/ml

Method:

Loinc: 15061-5

 

ESR (Erythrocyte Send. Rate)

The erythrocyte sedimentation rate (ESR), also called a sedimentation rate or Westergren ESR, is the rate at which red blood cells sediment in a period of one hour. It is a common hematology test, and is a non-specific measure of inflammation.

Specimen: Sodium Citrate

Reference Values:

Females: 0-20 mm/hour
Males: 0-15 mm/hour

Method: Westergren

Loinc: 4537-7

 

Estradiol

It is a type of estrogen hormone. It is named for and is important in the regulation of the estrous and menstrual female reproductive cycles. Estradiol is essential for the development and maintenance of female reproductive tissues but it also has important effects in many other tissues including bone.

Specimen: Serum

Reference Values:

Follicular Phase: 26.6-161 pg/ml
Pre-ovulatory: 187-382 pg/ml
Luteal Phase: 32.7-201 pg/ml
Post-Menopausal: 5.37-38.4 pg/ml
Adult Males: 5.37-65.9 pg/ml

Method: CLIA

Loinc: 14715-7

 

Extractable Nuclear Ag-ENA Abs

Extractable Nuclear Antigens are over 100 different soluble cytoplasmic and nuclear antigens. Autoantibodies to these antigens are associated with particular connective tissue disorders. The six main antigens used in immunological laboratories for detection are Ro, La, Sm, RNP, Scl-70 and Jo1.

Specimen: Serum

Reference Values:

Anti Jo-1 Antibody : <20 IU/ml

Anti Scl-70 Antibodies : <20 IU/ml

Anti SS-A/Ro Antibody : <20 IU/ml

Anti SS-B La Antibody : <20 IU/ml

Anti-RNP : <20 IU/ml
