This test measures a protein hormone produced by the placenta and ovaries to screen for fetal chromosomal abnormalities, like Down syndrome, during the second trimester of pregnancy. In non-pregnant individuals, it can also be used as a tumor marker to help diagnose and monitor certain types of ovarian cancers.
This test detects antibodies that your body's immune system mistakenly creates against insulin, helping doctors diagnose immune-mediated insulin resistance or evaluate the cause of unexplained low blood sugar (hypoglycemia). It is also commonly used to differentiate between Type 1 and Type 2 diabetes by identifying autoimmune destruction of insulin-producing cells.
This test measures the amount of IGF-1 in your blood to help diagnose growth disorders (like acromegaly or growth hormone deficiency) and evaluate pituitary gland function. Because IGF-1 levels mirror overall growth hormone activity but remain stable throughout the day, it provides a highly reliable snapshot of your body's hormone production
This test measures the level of HE4 protein in the blood to help monitor for the recurrence or progression of epithelial ovarian cancer in women who have already been diagnosed. When combined with a CA-125 test, it forms a risk assessment tool (ROMA) that helps doctors determine whether a pelvic mass is likely to be benign or malignant before surgery.
This toxicology test screens for the presence of MDMA (3,4-methylenedioxymethamphetamine) or its metabolites to detect recent use of the synthetic drug commonly known as ecstasy or molly. It is frequently used in emergency medical assessments, workplace drug screenings, forensic investigations, and substance abuse treatment monitoring
This test identifies the specific bacteria or fungi causing a deep lung infection (like pneumonia or bronchitis) by growing the microbes from your coughed-up phlegm. Once the organism is identified, susceptibility testing is performed to determine exactly which antibiotics or medications will be most effective at curing the infection.
This rapid laboratory test uses a special series of dyes on a bodily fluid or tissue sample to classify bacteria into two major groups: Gram-positive or Gram-negative. It provides quick, preliminary information about the presence and type of bacterial infection, allowing doctors to immediately start targeted antibiotic treatment while waiting for a full culture.
This toxicology test detects the presence of morphine or its metabolites to determine recent use of this potent opioid, whether it was prescribed for severe pain management or misused. It is widely used in clinical settings to monitor patient compliance, in emergency rooms to evaluate potential overdoses, and in standard workplace drug screenings.
This toxicology test screens for the presence of methaqualone (commonly known by the brand name Quaalude) to detect the use or misuse of this potent sedative-hypnotic drug. It is used in medical emergencies to evaluate potential overdoses, as well as in forensic investigations and comprehensive workplace drug screenings.
No, fasting is generally not required for a Direct Renin test, though your doctor may ask you to rest quietly for 15 to 30 minutes before the blood draw and follow specific instructions regarding your salt intake and blood pressure medications.
This test measures the precise concentration of active renin, an enzyme produced by the kidneys, to help diagnose primary aldosteronism and investigate the root cause of severe, unexplained high blood pressure. By evaluating how much renin is in your bloodstream, doctors can determine if an overproduction of hormones is disrupting your body's critical fluid, sodium, and blood pressure balances.
This test measures the amount of AAT, a protective protein produced by the liver, to help diagnose an inherited deficiency that can cause severe early-onset emphysema (lung disease) or liver damage. It is primarily used to evaluate individuals with unexplained respiratory symptoms, prolonged jaundice, or a family history of genetic lung and liver disorders.
This test measures the concentration of Chromogranin A, a protein secreted by neuroendocrine cells, to help diagnose, monitor, and evaluate the treatment response of neuroendocrine tumors (NETs) such as carcinoid tumors. It serves as a valuable tumor marker, though doctors will often advise temporarily stopping acid-reducing medications (like PPIs) prior to the test, as they can also falsely elevate these protein levels.
This test measures the exact concentration of ethanol (alcohol) or its specific markers in your system to determine recent alcohol consumption, impairment levels, or overall sobriety. It is commonly utilized in legal investigations (such as driving-under-the-influence cases), workplace safety evaluations, emergency medical screenings, and addiction recovery monitoring programs.
This immunological test detects specialized proteins that mistakenly target and damage sperm, which can cause them to clump together and impair their ability to swim or fertilize an egg. It is primarily used to investigate unexplained immunological infertility in both men and women when standard fertility evaluations do not reveal a clear cause.
This test measures holotranscobalamin, the specific and biologically active form of vitamin B12 that your body's cells can actually absorb and use. It serves as a highly sensitive, early biomarker to detect vitamin B12 deficiency well before standard B12 tests can spot a decline, making it crucial for evaluating unexplained anemia or neurological symptoms.
