"The Telegraph reports that James and John Parr were both arrested after watches worth £10,000 were stolen from a shopping center. Police found blood on a piece of glass at the scene of the crime and traced it back to the 25-year-old identical twins through DNA tests. But James and John both denied the theft and, because they have identical DNA, it has been impossible to prove beyond a reasonable doubt which twin is responsible. 'The police told us that they knew it was one of us, but we both denied it,' says James. 'I definitely know I didn't do anything wrong. I was watching my daughter that night.' Now the Crown Prosecution Service (CPS) has concluded that it cannot prove beyond reasonable doubt who was responsible. 'Unless further evidence becomes available, we are unable to authorize any charge at this time,' says CPS spokesman Rob Pett. 'This is certainly not something that we regularly encounter.' Identical twins have hindered police investigations a number of times since the advent of DNA testing. In Malaysia last year, a man suspected of drug-smuggling and sentenced to death was released when the court could not prove whether it was he or his twin brother who committed the crime."
The test that determines the compatibility of donor and recipient blood is called a blood typing test. This test identifies the specific blood type of an individual, focusing on the ABO blood group system and the Rh factor.
A PSR blood test measures the level of protein S, a protein that helps regulate blood clotting, in the blood. This test is often used to diagnose conditions related to abnormal blood clotting and to monitor treatment effectiveness.
A blood smear is a sample of blood that is spread thinly on a glass slide, stained, and examined under a microscope. It is used to evaluate the number, morphology, and size of different types of blood cells such as red blood cells, white blood cells, and platelets. This test helps in diagnosing various blood disorders and infections.
UEC blood test stands for Urea, Electrolytes, and Creatinine blood test. It measures levels of these substances in the blood to assess kidney function and hydration status. This test is commonly ordered to evaluate renal function in patients with various medical conditions.
A fasting blood glucose test (FBC) measures the amount of glucose in your blood after you have not eaten for at least 8 hours. This test is commonly used to diagnose diabetes or monitor blood sugar levels in individuals with diabetes. High levels of glucose in the blood can indicate diabetes, while low levels can be a sign of hypoglycemia.
The police usually test urine.
Blood clotting in test tubes due to glass occurs when the glass surface activates clotting factors present in the blood. The glass can cause physical trauma to the blood cells, triggering the clotting process. This can lead to ex vivo clot formation in blood samples collected in glass test tubes.
yes. a blood test is also more accurate than a breath test.
no. just a myth
Yes, blood can clot in a glass test tube because the tube provides a surface for the blood cells and proteins to adhere to and form a clot. Clotting can be prevented by using anticoagulants in the tube or by carefully handling the sample to avoid triggering the clotting process.

A hematology pit test, also known as a peripheral blood smear, is a laboratory test used to examine blood cells under a microscope. This test helps identify various conditions by assessing the shape, size, and number of red blood cells, white blood cells, and platelets. It can aid in diagnosing anemia, infections, blood disorders, and other hematological conditions. The test involves spreading a drop of blood on a glass slide, staining it, and then examining it for any abnormalities.
You can detect alcohol in the body with a blood test. You can also detect alcohol in the body, like police officers, by using a breathalyzer test.
