Lavander
A lavender tube of blood is typically collected for hematology tests, such as complete blood count (CBC) and blood cell differential analysis. The lavender top tube commonly contains ethylenediaminetetraacetic acid (EDTA), which helps preserve the blood for accurate analysis of cell counts and morphology.
Hemoglobin A1C is a blood test that is used to track the blood sugar of a diabetic over the past 3 months. The life of a red blood cell is approximately 3 months, and this test gives an average of blood sugar levels over that time.
The color of the test tube for A1C testing can vary, but it is commonly purple or lavender in color. This color helps to indicate the specific type of test being performed.
The hemoglobin A1c, or glycohemoglobin, is a measure of how much sugar is attached to the hemoglobin protein in the blood. Sine hemoglobin is removed from the blood along with the red cell in which it is resides measuring the a1c can give an estimate of ow high the sugar has been averaging over the life of the red cell, which is usually about 120 days (4 months). The most recent time frame has a larger effect on it than more distant times so it is often, somewhat inaccurately, said to give a 3 month average. It can be affected by anemia, blood loss, blood transfusions and abnormal hemoglobins.

The recommended tube for hemoglobin A1C testing is lavender or purple top tube, which contains EDTA as an anticoagulant. It is important to follow the specific instructions provided by the laboratory where the test will be performed.
Diabetes is caused by a hemoglobin a1c deficiency. Hemoglobin a1c tests are used in the diagnosis of diabetes.Monitoring the hemoglobin a1c in type-1 diabetic patients may improve treatment.

The recommended tube for A1C testing is a lavender/purple-top tube containing ethylenediaminetetraacetic acid (EDTA) as an anticoagulant. This additive prevents blood from clotting and preserves the sample for accurate testing of hemoglobin A1C levels.
You can get a hemoglobin a1c test completed at your local pharmacy. The purpose of the test is to measure your blood for the risk of very fatal diseases..
For people without Diabetes, the normal range for the hemoglobin A1c test is between 4% and 5.6%. Hemoglobin A1c levels between 5.7% and 6.4% indicate increased risk of diabetes, and levels of 6.5% or higher indicate diabetes. Because studies have repeatedly shown that out-of-control diabetes results in complications from the disease, the goal for people with diabetes is a hemoglobin A1c less than 7%. The higher the hemoglobin A1c, the higher the risks of developing complications related to diabetes. Source: WebMD

A1C is actually an abbreviation of another abbreviation, HbA1c. This is hemoglobin A1c and that is a blood test of a person's blood sugar levels to determine or evaluate diabetes.
A lavender-top (EDTA) tube is typically used for drawing blood samples for hemoglobin electrophoresis testing.
