Guessing you're asking about color coded vacutainers, since otherwise I can't make any sense of the question.
Light blue is usually the color code for a tube with sodium citrate.
Gray
Gray top tube
It is because sodium reacts with water (present in test tube or porcelain basin) to give a alkaline solution of NaOH.

its tube light only. Since the Hindi language doesnt have any specific word for it.
red
either SDS or ACD (Sodium polyanetholesulfonate) (Acid Citrate Dextrose)
Blue top tube which contains citrate.
Sodium Citrate, the same as Light Blue top tubes.
elevated glucose value
red top is plain tube, for clotted blood. purple top is edta tube, for blood cytology. grey top tube contain sodium flouride anti coagulant for blood sugar. green top tube contains heparin require for cd4, cd8, etc. sky blue top tubes contain sodium citrate 3.2% for bleeding disorder tests such as pti etc.
Black top (sodium citrate tube) or light blue tube. They both contain sodium citrate. I failed this question on my final, I knew a black top tube is used but it was not given to me as a choice. I did not think hard enough to come to the conclusion that a light blue tube would be another option.
Light yellow top tube contains the additive sodium polyanethol sulfonate (SPS) or acid citrate dextrose additives. This tube is used for blood bank studies, human leukocyte antigen (HLA) phenotyping, DNA, and paternity testing.
If bacterium cannot use glucose the fermentation tube will stay the same color. Gas may also occur inside the fermentation tube.
Red
A blue top blood tube contains buffered sodium citrate(buff. Na citrate). This chemical has three main functions: 1) To prevent blood from clotting 2) To preserve the shape of red and white blood cells 3) To prevent platelets from clumpingGenerally blue tubes are used for the following tests: Prothrombin Time (PT), Partial Thromboplastin Time (PTT/APTT) and International Normalized Ratio (INR).Hope that helps!
that would be the Green Top Tube that contains sodium heparin this tube also is to draw ammonia.
blue (citrate) tube
