Calcium is written as Ca and the ionized form of calcium is Ca2+ which indicates that it has a positive charge due to losing two electrons.
The recommended tube for calcium level testing is a lavender or royal blue top tube, as these tubes contain additives that preserve calcium levels effectively. It is important to follow the specific instructions provided by the laboratory where the testing will be conducted.
A SST tube, or Serum Separator Tube, is used to collect and separate blood samples for laboratory testing. The tube contains a gel that separates the serum (liquid portion of blood) from the blood cells when the tube is centrifuged, making it easier to analyze the serum for various tests.
The lavender-top tube or EDTA tube is typically used for Hgb A1c testing in phlebotomy. It helps prevent clotting by binding calcium ions.
A lavender/purple-top tube is commonly used for calcium testing.
Calcium loses 2 valence electron to become ionized.
Light blue tube with sodium citrate additive is used for bleeding and coagulation studies as it helps to prevent blood from clotting by binding calcium.
Calcium phosphate is typically white in color.
A starter initially provides a path to complete the circuit. The tube light starts when the current flows through the ionized gas in the main tube. woodenboatusa.com
The flame color of calcium chloride is typically a deep orange-red color. This color is due to the presence of calcium ions in the compound, which emit this characteristic color when heated.
The streak color of the mineral calcium is white.
