A test tube rack is a piece of laboratory equipment used to hold and organize test tubes. It typically has openings where test tubes can be inserted securely in an upright position. Test tube racks are used to store, transport, or organize test tubes during experiments and laboratory work.
According to the American Heritage Dictionary of the English Language, a test tube is a "clear, cylindrical glass tube usually open at one end and rounded at the other, used in laboratory experimentation."A test tube can be used to store chemicals that are dangerous to skin,or be connected to other lab equipment for experiments. In this case, it is usually to collect a useful product.
Test tube racks are typically made of metal, plastic, or wood to hold test tubes in place and keep them organized during experiments or storage. They come in various sizes and configurations to accommodate different numbers and sizes of test tubes. The material used depends on the desired durability, chemical resistance, and safety requirements of the laboratory setting.
A test-tube holder, also known as test-tube clamp or test-tube rack, is used to hold a test tube over a Bunsen burner during heating. It is designed to ensure safe handling and prevent accidents while working with test tubes and heat sources.
A purple or lavender-colored top tube with EDTA anticoagulant is typically used for collecting samples for a shingles test.

The test tube for an HDL cholesterol test is typically clear or transparent. This allows for easy visualization of the sample and measurement of the cholesterol levels in the blood.
The test tubes used for collecting blood for a cholesterol test are typically red or gold-topped tubes. These tubes contain a gel separator to separate the serum from the blood cells after centrifugation, allowing for accurate measurement of cholesterol levels in the serum.
The color vacutainer tube typically used for cholesterol testing is the gold or tiger-top (SST) tube, which contains a serum separator gel. Alternatively, a light green tube (lithium heparin) can also be used for certain cholesterol tests. These tubes help separate the serum from the blood cells after centrifugation, allowing for accurate measurement of cholesterol levels.

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.
A red tube with no anticoagulant is typically used for an AFP test.
