This test measures the levels of the NAG enzyme in the urine to detect early kidney damage or injury, specifically targeting the cells of the renal tubules. Because NAG is too large to pass through a healthy kidney filter, an elevated level serves as a sensitive biomarker for tubular dysfunction caused by conditions like diabetes, hypertension, or toxic drug exposures.
This test measures the concentration of phenobarbital in your blood to ensure the drug remains within a safe, therapeutic range for controlling seizures and epilepsy. Because individual metabolism varies, doctors use these levels to optimize your dosage and prevent severe side effects like extreme drowsiness or toxicity.
This test measures prealbumin levels to quickly assess and monitor your nutritional status and determine if your body is getting enough protein, making it highly useful for evaluating patients recovering from severe illness, surgery, or chronic malnutrition. Because prealbumin has a very short half-life of only 2 to 3 days, it reflects recent changes in your nutritional intake much faster than a standard albumin test.
No, fasting is not required for a Properdin Factor B test; you can eat and drink normally before your blood is drawn.
This test measures the level of Factor B—a crucial protein in the immune system's alternative complement pathway—to help diagnose and monitor autoimmune diseases and chronic infections. A deficiency or abnormal consumption of this protein can indicate increased susceptibility to recurrent infections or a tendency toward severe kidney inflamm
This test screens for the presence of propoxyphene and its primary breakdown product, norpropoxyphene, to detect use or monitor for toxic levels of this prescription opioid painkiller. Propoxyphene is a central nervous system depressant that was largely discontinued in many countries due to severe risks of heart arrhythmias, dependency, and accidental overdose.
This test detects specific IgG antibodies to confirm an infection caused by the Echinococcus tapeworm, a parasitic disease known as hydatid disease that causes slow-growing fluid-filled cysts to form in the liver, lungs, or other organs. It is primarily used to evaluate patients who show cyst-like masses on imaging scans or who have had potential exposure to infected farm animals or dogs.
This test detects specific IgG antibodies to determine if you have a current or past extra-intestinal infection from Entamoeba histolytica, a parasite responsible for amebiasis and severe liver abscesses. It is highly effective for differentiating parasitic tissue invasions from other non-parasitic causes of liver or bowel inflammation.
This test measures the amount of ethanol (alcohol) in your system to evaluate medical emergencies, monitor addiction recovery programs, or address legal and workplace safety concerns. It accurately calculates blood alcohol concentration to determine intoxication levels or to verify total sobriety.
This test measures the concentration of digoxin in your blood to ensure your dose is within a safe, therapeutic range for treating heart failure and certain abnormal heart rhythms like atrial fibrillation. Because digoxin has a narrow therapeutic window, monitoring these levels is critical to prevent dangerous toxicity while maintaining effective heart function.
This rapid screening test detects total core antibodies (anti-HBc) to determine if you have a past or current infection with the Hepatitis B virus. Because these antibodies develop during an acute infection and typically persist for life, the test is a crucial tool for identifying individuals who have been exposed to the virus, even if they have cleared it naturally.
This rapid test detects the HBeAg protein in the blood to determine if the Hepatitis B virus is actively replicating and if you are highly contagious. It is used by clinicians to monitor the infectivity of chronic carriers and to gauge how effectively the virus is responding to antiviral treatments.
This rapid test detects antibodies against the Hepatitis B "e" antigen to signal that the virus is no longer actively replicating and your level of infectivity has significantly decreased. It is primarily used by doctors to monitor the progression of a chronic infection and to confirm a positive shift toward a less active, lower-risk stage of the illness.
This test measures the level of haptoglobin, a protein produced by the liver, to detect and monitor hemolytic anemia, a condition where red blood cells are destroyed faster than your body can replace them. When red blood cells break down, they release free hemoglobin into the bloodstream, which binds to haptoglobin and causes the protein's overall levels to drop significantly.
This highly sensitive molecular test measures the exact amount of HBV DNA (viral load) in your blood to evaluate how actively the virus is multiplying. It is crucial for doctors to determine the severity of a chronic infection, decide when to start antiviral therapy, and monitor how effectively your body is responding to treatment.
This serology test detects IgM antibodies to identify a recent or acute infection by the H. pylori bacteria, which commonly attacks the stomach lining and causes chronic inflammation. It is used as an initial screening tool for patients experiencing new-onset symptoms like burning stomach pain, bloating, or suspected peptic ulcers.
