The blood test that is light sensitive is the bilirubin test, which measures the levels of bilirubin in the blood. Bilirubin is a byproduct of the breakdown of red blood cells, and exposure to light can cause it to degrade, potentially leading to inaccurate results. To prevent this, samples should be protected from light, typically by wrapping them in aluminum foil or using special light-blocking tubes.
The blood chemical constituant that is light sensitive is Bilirubin..
Yellow test tubes are commonly used for tests that require light protection, like those sensitive to UV light. They are also used for tests that involve urine or blood samples that need to be protected from light exposure or degradation. Additionally, yellow tubes may be used in laboratories to distinguish specific tests or protocols.
Yes, they are sensitive to light.
Yes. The fecal occult blood test is not very sensitive, so it won't detect most cases of colon cancer.

Some blood test tubes need to be put on ice to preserve the integrity of certain lab tests that are sensitive to temperature changes. Cooling the tubes helps slow down the degradation of certain components in the blood and ensures more accurate test results.
Yes, it's OK! Just rang the medical centre and they said it's fine to have a blood test when you've got your period UNLESS your doctor has instructed otherwise. If you get light-headed easily or have heavy periods, it might be good to take along a cereal bar or something that you can have after your blood test!
There is a bedside version of the test in which the doctor collects four or five drops of blood in a small tube, cools the tube in ice water for 30-60 seconds, and looks for clumping of red blood cells.
Test tubes are typically made of clear glass or plastic to allow for easy visibility of the contents being tested. In some cases, test tubes may come in different colors to suit specific experimental needs, such as amber tubes for light-sensitive substances or red tubes for blood collection.
It is possible that you can be pregnant with negative HPT results because sometime the level of HCG hormone that the test is supposed to detect could be too low. You need to buy a pregnancy test that says that is it for early detection or is very sensitive. It will have a number on it, I believe the most sensitive is 20 mIU/mL. Look for this number on the package. Or you can go to your doctor or clinic and get a much more accurate blood test done.
The retina at the back of the eye is light-sensitive.
Probably pregnant, go get another test or go to your doctor to get a blood test.
