Glucose tolerance tests are used to diagnose diabetes. A random blood glucose test should show levels below 200 mg/dL, while fasting plasma tests should have results of 60 to 99 mg/dL. The oral glucose tolerance test (OGTT) results vary based on the type of diabetes being screened for. Pregnant women undergo an OGTT to screen […]
Testing for Asperger’s syndrome involves multiple assessments, including psychological, communication, and psychiatric evaluations. Tests may include an IQ test, CAST, DSM-IV, and AQ. A normal IQ does not rule out Asperger’s, and a single test is not enough for a diagnosis. Testing for Asperger’s syndrome typically requires a litany of tests because there is no […]
Paternity tests can establish biological fatherhood for financial aid, child support, and legal matters. Tests must be taken in court-approved locations by authorized officials, and laws vary by state. Home tests are not official. A paternity test may be ordered when a woman wants to prove that a particular man is the father of her […]
A request for evidence (RFE) is a form submitted by USCIS requesting additional documentation from visa applicants. It may mean updating or clarifying information, and has a deadline for submission.

Summary trials are an alternative dispute resolution that provides parties with an idea of how a real jury would decide a case. They are conducted in ordinary courtrooms with a strict one-day time limit and often a non-binding verdict. Summary trials are meant to help parties settle without going to trial, saving time and money. […]
The “rabbit test” was a method of testing for pregnancy in the 1920s by injecting a woman’s urine into a female rabbit. The rabbit’s ovaries would show changes if the woman was pregnant, but the rabbit would have to be killed to examine the ovaries. The test was later revised to check ovarian changes on […]
Urine tests can detect legal and illegal drugs, and the only way to pass is to have no drugs in your system. Flushing, dilution, adulteration, masking, and urine replacement are illegal methods to pass a test, but they are unreliable and can be easily detected. Urine tests for medications are often given to people due […]
Breath tests diagnose diseases by analyzing air expelled from the lungs. Common types include breathalyzers, exhaled nitric oxide tests, hydrogen breath tests, and urea breath tests. Hippocrates recognized the relationship between breath and health, and Linus Pauling found 250 chemicals in human breath. Breathalyzers determine blood alcohol content, while other tests identify asthma, dietary diseases, […]
The Vickers hardness test, developed in 1925, uses mechanical force to determine the hardness of materials. A diamond tip is used to create an indentation, and the force applied is measured using a digital gauge. The hardness number is obtained by dividing the force by the diagonal mean squared. Vickers hardness testing devices can be […]
Probation is a court order given to convicted defendants as an alternative to prison. Violating probation conditions may result in return to prison. Compliance with probation can lead to elimination of a criminal record. Probation requires the person to live a normal, lawful life and may include regular meetings with a probation officer, drug testing, […]
A food hygiene test assesses how food is handled, prepared, and stored for public consumption. A trained food inspector evaluates staff, kitchen cleanliness, and food quality to ensure safety and sanitation. The test can result in fines or action against the establishment if failed. A food hygiene test – also called a food inspection – […]
DNA testing uses cheek swabs to collect genetic material from cells, which can determine paternity with 99.99% accuracy. The test is non-invasive and can be performed on newborns. Home versions are available but not legally binding, and court-ordered tests must be done under controlled circumstances. A DNA test examines the genetic material, deoxyribonucleic acid (DNA), […]
Genetic paternity testing is highly accurate, with two types of tests: an exclusion test to determine if a man could be the father, and an inclusive test to determine if he is. The inclusive test is usually over 99% accurate, but there is always some margin of error. Mothers can also be tested to increase […]
The complement fixation test detects specific antibodies in blood and is used to diagnose autoimmune diseases or monitor chronic conditions. The test measures how quickly antibodies react to complement and can be used to measure the effectiveness of treatment for autoimmune diseases. It is also useful for diagnosing central nervous system infections. The complement fixation […]
Gluten allergy testing involves blood tests to rule out other conditions, a skin test to determine if an individual has a true gluten allergy, and an elimination diet to confirm the allergy. Once confirmed, an individual’s diet must be modified to exclude gluten. A gluten allergy test generally consists of a series of procedures to […]
Pile tests use motion and sound sensing to evaluate concrete pile integrity and locate defects. The ASTM Standard – D 5882-00 is used to standardize testing. Sonic recording and echo tests are used to test battery integrity. The length and standing time of the concrete post is determined by sound wave speed. Various methods are […]
The Epstein-Barr IgG test is a blood test that looks for the Epstein-Barr virus, which is transmitted through saliva. The test is noninvasive, but individuals may experience some discomfort during the blood draw. The test is used to diagnose ongoing or previous infections, and symptoms may include fever, sore throat, and fatigue. If the test […]
A hepatitis blood test detects antibodies made by the body in response to the virus. It helps identify the type of virus causing the infection and can be used to screen healthcare professionals and blood donors. Different forms of hepatitis can be determined through the test. Prevention and treatment depend on the type. A hepatitis […]
Governments including the US, Russia, UK, France, China, India, Pakistan, North Korea, South Africa, and possibly Israel have tested nuclear weapons at various sites. The first nuclear test sites were in New Mexico and Nevada, with the first-ever nuclear weapon detonated in New Mexico in 1945. Nuclear testing continued with Operation Crossroads in the Pacific, […]
Vibration testing is used for quality control and field monitoring of products, such as pumps and motors. Testing can be done with a shaking unit or on a vibration testing machine, and can be uni-directional or multi-directional. Designing for vibration protection includes creating strong parts and packaging, and testing containers for strength and vibration resistance. […]
