Polygraph tests, also known as “lie detector tests,” are commonly used in criminal investigations and background checks. The machine measures physical responses to questions, such as heart rate and perspiration. However, the accuracy of the test is controversial and can be cheated with proper training. Also known as a “lie detector test,” a polygraph test […]
A cerebrospinal fluid test analyzes the fluid around the brain and spinal cord to diagnose central nervous system disorders. A lumbar puncture is the most common method of extraction, but in rare cases, a cisternal or ventricular puncture may be necessary. The fluid is examined for color, consistency, protein levels, and other substances to accurately […]

Understanding STD test results can be confusing. “Positive” means signs of an STD were found, “negative” means no signs were found. “Inconclusive” terms like “equivocal” or “indeterminate” mean the test was inconclusive. “Reference range” and “value” are also included in results. False positives or negatives can occur, so tests may need to be repeated. When […]
Urine pH can indicate overall health and reveal health problems such as kidney stones, infections, and kidney problems. Alkaline urine can be caused by kidney failure, while acidic urine can be caused by diarrhea, COPD, or certain medications. A urine pH test can prevent kidney stones and increase medication effectiveness. A balanced diet should be […]
The Wonderlic personnel test (WPT) is a short test that provides insight into a candidate’s intellectual strengths and weaknesses as they relate to the requirements of a particular job or assignment. It consists of a series of English, reading, math and logic problems that increase in difficulty as the test progresses and can be administered […]
An eye coordination test measures the relationship between visual and physical responsiveness, which is crucial for motor skills such as writing, reading, and sports. Poor eye coordination may cause headaches, eye strain, and dizziness, but can be treated with vision therapy, medication, and wearing sunglasses. Regular sporting activity can improve coordination, and measuring eye coordination […]
Endotoxin tests detect lipopolysaccharides in a sample, which are produced by Gram negative bacteria and can cause health issues like septic shock. Manufacturers use the test to ensure product safety, while research labs use it to verify sample purity. The classic test uses a compound from horseshoe crab blood to detect endotoxins. Contamination can be […]
Standardized test scoring methods include percentages, averages, grade-level norms, specific performance requirements, and raw scores. Multiple-choice questions are common, and tests are usually evaluated by computer programs. Raw scores can be converted to percentages, and averages are used in some tests, such as the IQ test and graduate program exams. Grade-level averages compare scores to […]
Blood sugar levels can be tested at home using urine or blood tests, with blood tests being more accurate. Normal levels are between 70-100 mg/dL for non-diabetics and 90-130 mg/dL for diabetics. A glucometer is used for blood tests, while urine tests require specialized strips. Testing blood sugar levels can be done in several ways. […]
Electrolyte tests measure levels of potassium, sodium, bicarbonate, and chloride in the blood, which play a crucial role in regulating fluid levels in the body. Imbalances can cause weakness, abnormal heartbeat, and fluid retention, and can be caused by dehydration, kidney failure, and diabetes. Treatment includes changes in diet, medication, and regular testing. An electrolyte […]
