The ANA test detects antinuclear antibodies in the blood, which can indicate autoimmunity. It is commonly used to diagnose lupus and other autoimmune disorders. ANA patterns can also provide insight into certain diseases, but are not specific to any one condition. ANAs can also be present in patients without autoimmune diseases, and can be drug-induced. […]
Cyclic testing involves repeated testing of a product to confirm its reliability and simulate real-world conditions. It can demonstrate a product’s performance over time and under stress, and is important for reliability testing. Testing can be done in-house or at a materials testing facility. A cyclic test is a type of test in which a […]
A microalbumin test measures protein levels in urine to evaluate kidney function, commonly used to diagnose microalbuminuria in individuals with high blood pressure or diabetes. Abnormal results indicate impaired kidney function, requiring further testing to determine the extent of damage. The test can be done at home or in a medical setting, with strict instructions […]
A urine alcohol test detects whether a person has consumed alcohol and can determine the time frame of ingestion. It is commonly used for workplace safety and probation. The test can detect alcohol in the urine for 6-24 hours after consumption, and an extended version can detect alcohol use up to 5 days prior. Other […]
In-circuit testing ensures proper manufacturing and quality in PCBs. The bed of nails test is the most common method, using connector pins to test for electrical problems. There are pressure and vacuum bed-of-the-nail testers, with vacuum being more efficient but expensive. The test can help find faults, but cannot test PCB contacts or durability. An […]
An EEG measures electrical activity in the brain and is commonly used to diagnose seizure disorders. It can also be used to evaluate other conditions, but results can be affected by patient compliance. Variations in brain activity may require further testing for confirmed results. An electroencephalogram (EEG) evaluates the electrical activity produced by the brain, […]
A test analyst runs various tests on a company’s products and processes, documents any issues found, and may create new tests and databases. They also design tests, develop testing strategies, and work with others to implement solutions to problems. Documentation and helping with the development of solutions may also be part of their job. A […]
Blood tests can help diagnose medical conditions such as anemia, leukemia, and bacterial infections. A complete blood count measures red and white blood cell counts, hemoglobin, platelets, and hematocrit levels. A chemistry panel can detect liver, kidney, or thyroid gland problems, electrolyte imbalances, and pancreatic problems. Other blood panels may be prescribed for specific cases. […]
Personality tests measure psychological traits and behavior, used in the workforce to evaluate potential employees. There are different types of tests, including projective and questionnaire-based tests. The use of personality tests in the workplace has been criticized, and the Forer effect may explain their popularity. A personality test is a test that measures different aspects […]
The BNP test measures levels of B-type natriuretic peptide in the blood, which increases as heart failure worsens. It is a minimally invasive and cost-effective diagnostic test, but other factors such as drug therapies, age, and kidney disease can cause elevated levels. A positive test result requires further follow-up and diagnostic testing. A BNP test […]
The Ames test is a bioassay that determines the likelihood of mutagenic activity in chemicals. Bacteria, specifically Salmonella typhimurium, is used to perform the test. A positive result indicates the chemical may be a carcinogen and requires further investigation. The test is named after its developer, Bruce Ames. The Ames test is a type of […]
Aggregate test equipment is crucial in the building industry to determine the particle size, shape, texture, density, mechanical properties, and chemical resistance of aggregates. This equipment includes crushers, conveyor belts, screens, sieves, and agitators, which are used to process materials for building applications and infrastructure. The equipment tests the suitability of aggregates for specific applications, […]
The poppy seed test is used to diagnose colo-bladder fistulas, which are abnormal pathways between the bladder and colon. It provides 100% accuracy and is significantly less expensive than other diagnostic methods. In medicine, doctors typically administer the poppy seed test to pre-operative patients suspected of having a colo-bladder fistula, which is an abnormal pathway […]
The bend test determines if a metal will crack under pressure. It measures the metal’s ductility, or ability to bend without breaking. Results vary by material group. Bend test machines are used to perform the test. Copper and steel have high ductility and perform well under pressure. A bend test is used to determine whether […]
An anchor test assesses a person’s knowledge or cognitive abilities by testing the same skill or ability in multiple ways to determine if a question was missed due to a gap in knowledge or a misunderstanding of the question. Psychometrists use anchor tests to reliably test skills and eliminate inconsistencies. Traditional tests reveal missing skills, […]
Alcohol saliva tests use a strip of material saturated with saliva to determine blood alcohol levels. They are reliable and accurate, easy to use, and can be purchased in boxes of 6 to 100. They are commonly used by employers, parents, and individuals to ensure safety and avoid dangerous situations. An alcohol saliva test is […]
A guaiac test detects abnormalities in fecal matter to diagnose gastrointestinal tract dysfunction. It is often used to check for bloody stools, which can indicate colon problems, infections, and inflammatory bowel disease. Preparatory steps and dietary restrictions may be required, and false results are possible due to poor sample collection or contamination. Home collection techniques […]
Manufacturing test engineers design and develop test procedures and equipment to ensure quality and reliability of electronic products. They also analyze test results, make recommendations for improvements, and serve as liaisons between different departments. A bachelor’s degree in electrical engineering or computer science is typically required. In the electronics manufacturing industry, products must be tested […]
The glucose tolerance test checks blood glucose levels for gestational or type 2 diabetes. The patient fasts for 8 hours, drinks a glucose solution, and has blood drawn. Results are compared to normal levels and can indicate diabetes or other health problems. Results can be affected by illness, stress, or medications. The glucose tolerance test […]
Electromagnetic testing uses electricity and magnetic fields to detect defects in objects. Different tests have varying applications and methodologies, with some using both electricity and magnetic fields. The tests can also determine material properties and thickness. Examples of electromagnetic testing include pulsed eddy current testing for pipes and magnetic flux leakage testing for metal containers. […]
