Serum chromium is a test for abnormal levels of chromium in the blood.
Alternative NamesChromium blood test
How the test is performedBlood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The site is cleaned with germ-killing medicine (antiseptic). The health care provider wraps an elastic band around the upper arm to apply pressure to the area and make the vein swell with blood.
Next, the health care provider gently inserts a needle into the vein. The blood collects into an airtight vial or tube attached to the needle. The elastic band is removed from your arm.
Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.
In infants or young children, a sharp tool called a lancet may be used to puncture the skin and make it bleed. The blood collects into a small glass tube called a pipette, or onto a slide or test strip. A bandage may be placed over the area if there is any bleeding.
How to prepare for the testNo special preparation is necessary for this test.
How the test will feelWhen the needle is inserted to draw blood, you feel moderate pain, or only a prick or stinging sensation. Afterward, there may be some throbbing.
Why the test is performedThis test may be done to diagnose chromium poisoning or deficiency.
Normal ValuesSerum chromium levels normally range from less than 0.05 up to 0.5 micrograms/milliliter (mg/mL).
The range of normal values depends on the type of specimen tested and may vary between different laboratories.
What abnormal results meanIncreased chromium levels may result if you are overexposed to the substance when you work in the following industries:
Decreased chromium levels usually occur in people who receive all of their nutrition by vein (total parenteral nutrition or TPN).
What the risks areVeins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.
Other risks associated with having blood drawn are slight but may include:
Test results may be altered if the sample is collected in a metal tube.

A serum separator tube (SST) typically yields serum after centrifugation. It contains a gel barrier that separates the serum from the clot during the centrifugation process, allowing for easy collection of the serum layer.
A serum separator tube is a type of blood collection tube that contains a gel at the bottom to separate blood cells from serum during centrifugation. After spinning, the gel forms a barrier between the serum and the blood cells, making it easier to collect and analyze the serum for various tests.
Blood serum can be obtained by collecting a blood sample from a vein and allowing it to clot. The sample is then centrifuged to separate the serum from the rest of the blood components. Serum is the liquid component of blood obtained after clotting, which does not contain cells or clotting factors.
The gel in a serum separating tube acts as a barrier between the serum and the blood cells after centrifugation. It helps to separate the serum from the blood cells, making it easier to collect a clean sample for further analysis.
The color of the test tube for serum is typically red or gold. Red top tubes contain a clot activator and are used for collecting serum for various blood tests. Gold top tubes have a clot activator and serum separator gel to aid in separating serum from other blood components.
Serum is serum
Plasma minus clotting proteins is called serum. Serum is the liquid portion of blood that remains after blood has clotted and the clotting factors have been removed. Serum is used in various medical tests to measure different components in the blood.
Serum is generally free from blood cellular components but when collecting serum sometimes few cells will be pipetted with the serum & that is the only source of DNA in the serum.

There's just not enough serum for the two of us, dear. The serum is in the silver vial.
What are you testing for in the serum?
Yes, serum does contain antigens
serum
Blood plasma minus fibrinogen is known as serum. Serum is the liquid component of blood that remains after blood clotting (coagulation) has occurred and the fibrinogen, which is essential for clotting, has been removed. Serum contains electrolytes, antibodies, hormones, and any exogenous substances.

sera is the plural of serum!
