• Epcam A genetic test looking for changes in the EPCAM gene, which can switch off the neighboring MSH2 gene and are a recognised cause of Lynch syndrome.
• Epicoccum purpurascens (m14) IgE Measures IgE antibodies to Epicoccum, an outdoor mold found on plants and decaying vegetation, to check for allergic sensitization to its spores.
• Epstein-Barr Virus Early Antigen (EA) Antibody (IgG)EA An antibody that rises during active or recent Epstein-Barr virus infection and typically fades over time, helping pinpoint how recent an infection is.
• Epstein-Barr Virus (EBV) DNA, Detection A PCR test showing whether Epstein-Barr virus DNA is present in your sample, used to look for active or reactivated EBV infection.
• Epstein-Barr Virus (EBV) DNA, Viral Load The amount of Epstein-Barr virus DNA per volume of sample, used to measure and track EBV viral load, especially in people with weakened immunity.
• Epstein-Barr Virus (EBV) DNA, Viral Load (Log) The amount of Epstein-Barr virus DNA in your sample, reported on a logarithmic scale, used to measure and follow EBV viral load over time.
• Epstein-Barr Virus Nuclear Antigen (EBNA) Antibody (IgG)EBNA An antibody that appears months after Epstein-Barr virus infection and persists for life — its presence indicates a past, not recent, infection.
• Epstein-Barr Virus Viral Capsid Antigen (VCA) Antibody (IgG)VCA An antibody indicating past infection with Epstein-Barr virus (the cause of mono); usually stays positive for life.
• Epstein-Barr Virus Viral Capsid Antigen (VCA) Antibody (IgM)VCA An antibody that appears early in Epstein-Barr virus infection, helping identify a recent or current case of mono.
• Erythrocyte Sedimentation Rate (ESR), Modified WestergrenESR A general, non-specific marker of inflammation, based on how quickly red blood cells settle in a test tube. Elevated with many inflammatory, infectious, or autoimmune conditions.
• Esterified/Free Ratio A ratio calculated from esterified (acyl) carnitine and free carnitine in serum, used to help assess carnitine status and how fats are being processed.
• Estimated GFR An estimate of how well your kidneys filter blood, calculated here from cystatin C along with factors such as age and sex.
• Estimated Glomerular Filtration RateeGFR Estimated glomerular filtration rate — a calculated estimate of how well your kidneys are filtering waste from your blood, based on creatinine and other factors.
• Estradiol, Ultrasensitive, LC/MS A more precise version of the estradiol test, able to detect the very low levels typical in men, children, and postmenopausal women.
• EstriolE3 A form of estrogen produced mainly during pregnancy by the placenta. Used in prenatal screening for certain fetal conditions.
• Estrogens, Total, Immunoassay Measures your combined estrogen levels (estradiol, estrone, and estriol together), giving an overall picture of estrogen status.
• EstroneE1 One of the three main forms of estrogen, produced mainly by fat tissue and more prominent after menopause. Reflects overall estrogen status.
• Eucalyptus (t18) IgE Measures IgE antibodies to eucalyptus tree pollen to check for allergic sensitization that may explain seasonal hay fever or asthma symptoms.
• F2-Isoprostane A marker of oxidative damage to fats in the body, measured in urine to help assess your overall level of oxidative stress.
• F2-Isoprostane/Creatinine Ratio F2-isoprostane in urine divided by urine creatinine, a corrected marker of oxidative damage to fats used to assess overall oxidative stress.
