Phlebotomists typically use purple or lavender-top tubes containing EDTA (ethylenediaminetetraacetic acid) for drawing blood samples for A1C tests. These tubes help preserve the blood sample for accurate analysis of hemoglobin A1C levels. In some cases, a green-top tube with heparin may also be used, but the purple tube is the most common choice.

A gold or red-stopper tube is typically used when drawing a lipid profile. These tubes contain a clot activator to separate serum from blood cells during the centrifugation process.

Hemoglobin; by copper sulfate method, non-automated, glycosylated (A1C)(For glycosylated [A1c] hemoglobin analysis, by chromatography, in the setting of an identified hemoglobin variant, use 83021)(For fecal hemoglobin detection by immunoassay, use 82274)Taken from CPT 2011, courtesy AMA.

To split a blood sample in phlebotomy, first ensure you have properly labeled and prepared multiple collection tubes or containers. After drawing the blood, immediately transfer the required volume into the designated tubes, which may include serum, plasma, or whole blood tubes, depending on the tests to be performed. Use aseptic techniques to avoid contamination, and ensure that the tubes are mixed gently if they contain anticoagulants. Finally, securely cap the tubes and label them accordingly for accurate identification and processing.

As most plastics used in specimen tubes will melt if sterilized with heat the plastic tubes are normally single use

One can find an a1c chart at a doctors or in a hospital. It is used for diabetics and should a patient want one for their own use at home, it is simple to search for one on the internet and print one off.
It is not recommended to use peroxide in the ears with tubes installed as it can potentially damage the tubes or cause irritation to the ear canal. It is best to consult with a healthcare provider for proper guidance on ear care when tubes are present.
