This change in color indicates a chemical reaction taking place in the test tube. The specific reaction that caused the color change would depend on the substances present in the test tube and their chemical properties.
The list of diagnostic tests mentioned in various sources as used in the diagnosis of Dengue feverincludes: 1.Blood tests 2.Dengue virus lood test 3.Dengue antibodies blood test
The colour tube commonly used for fasting blood tests is usually a plain red or gold-top tube. These tubes do not contain any additives that could affect the results of fasting blood tests.

Heating a test tube may cause a color change because it can initiate a chemical reaction, causing substances in the test tube to change in structure or composition. This can lead to the formation of different colored products or the decomposition of the original substance into products with different colors.

The blood specimen for a CRP test is usually collected in a lavender-top or clear tube with an EDTA anticoagulant. This tube is also sometimes referred to as a "purple-top" tube.

The confirmation test for dengue typically involves serological assays that detect specific antibodies (IgM and IgG) or viral RNA. The most common tests include the Dengue NS1 antigen test, which identifies the presence of the virus early in the infection, and PCR (polymerase chain reaction) tests that detect viral RNA. Additionally, a dengue-specific IgM test can confirm recent infection, while IgG indicates past exposure. A combination of these tests helps in accurate diagnosis and management of dengue fever.
A light blue blood tube, also known as a sodium citrate tube, is typically used to test the International Normalized Ratio (INR). The sodium citrate acts as an anticoagulant, preventing blood from clotting so that accurate measurements can be obtained.
A test tube holder, also known as test tube clamp or test tube rack, is used to hold a test tube in place when the tube is hot or should not be touched. It allows safe handling of test tubes during heating or when conducting chemical reactions.
