The antiparietal cells antibodies test measures the presence of antibodies against the parietal cells of the stomach. The parietal cells make and release intrinsic factor and stomach acid. Intrinsic factor is needed to absorb vitamin B12.
Alternative NamesAPCA; Anti-gastric parietal cell antibodies
How the test is performedBlood is typically 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.
The blood is sent to the lab, where the liquid portion of the blood (serum) is separated from the cells. A sample of the serum is placed on a slide with samples from a mouse kidney and stomach, which contain parietal cells. If your serum contains parietal cell antibodies, these antibodies will react with the parietal cells on the slide.
How to prepare for the testNo special preparation is necessary.
Why the test is performedYour health care provider may use this test to help diagnose pernicious anemia. Other tests are also used to help with the diagnosis.
Normal ValuesThe test is negative.
What abnormal results meanA positive test result may indicate:
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:
- Excessive bleeding
- Fainting or feeling light-headed
- Hematoma (blood accumulating under the skin)
- Infection (a slight risk any time the skin is broken)
Less than 2% of the general population test positive for antiparietal cell antibodies. However, that percentage increases with age. Some people over age 60 may test positive for antiparietal cell antibodies.
Persons with other immune disorders such as thyroiditis and type 1 Diabetes may also have antiparietal cell antibodies.

How is the antinuclear antibody test prepared?
The antinuclear antibody test is done by adding a person's serum to commercial cells mounted on a microscope slide. If antinuclear antibodies are in the serum, they bind to the nuclei of cells on the slide.
Hemagglutination-inhibition test description?
It is the measures of the ability of soluble antigen to inhibit the agglutination of antigen-coated red blood cells by antibodies. In this test, a fixed amount of antibodies to the antigen in question is mixed with a fixed amount of red blood cells coated with the antigen (research on passive hemagglutination). Also included in the mixture are different amounts of the sample to be analyzed for the presence of the antigen. If the sample contains the antigen, the soluble antigen will compete with the antigen coated on the red blood cells for binding to the antibodies, thereby inhibiting the agglutination of the red blood cells.
You had blood test it showed you have antibodies in your blood?
blood test for antibodies ANA TEST Antibodies are often a sign of an infection best thing to do is talk to your doctor
What is a ana colorzyme hep 2 cells test result?
The Ana Colorzyme Hep-2 Cells test is a diagnostic test for autoimmune diseases that cause the body to attack its own cells. Results of the test will indicate the presence or absence of antinuclear antibodies (ANA) in the blood, which can help diagnose conditions like lupus or rheumatoid arthritis. Positive results suggest an autoimmune disorder, while negative results indicate the absence of these antibodies.
What is a Coombs' test?
An indirect Coombs' test looks for antibodies to someone else's red blood cells in the patient's serum
What causes unknown antibodies I had a blood test and the result showed that I had unknown antibodies in my blood. A subsequent test revealed that I have K red cells. Any light on what caused this?
With "unknown antibodies" you might mean irregular antibodies. In this case probably anitibodies against K (anti-K) a subtype of the Kell-bloodtype. Causes could be (including but not limited to): - You got a transfusion of bloodcells - You were pregnant
What does Coombs indirect mean?
Coombs indirect refers to the indirect Coombs test, a laboratory procedure used to detect antibodies against red blood cells in a patient's serum. This test is commonly employed in blood transfusion compatibility testing and in diagnosing hemolytic anemia or Rh incompatibility in pregnancy. By mixing the patient's serum with red blood cells of known antigenicity, the test identifies whether antibodies are present, which could lead to agglutination of the red blood cells.
Is a complete blood count a type of serologic test?
No, a complete blood count (CBC) is a laboratory test that provides information about the different components of blood, such as red blood cells, white blood cells, and platelets. A serologic test, on the other hand, looks for antibodies or antigens in the blood to determine an immune response to an infection or disease.
What happens if anti-B antibodies are mixed with group B red cells?
If anti-B antibodies (from someone who is blood type A or AB) are mixed with group B red cells, agglutination or clumping of red cells will occur due to a reaction between the antibodies and the B antigen on the red cells. This can lead to transfusion reactions if incompatible blood is transfused, causing harm to the recipient.
What are the purpose of agglutination test?
Agglutination serves to provide an idea of the presence of certain antibodies within the body. If specific antibodies against the antigen are present, the antibodies will combine with the antigens, coat the cells and cause the cells to join together, or agglutinate. It can be used to identify unknown antigens in diagnosing infections and to determine matching tissue types and blood groupings between two individuals.
What is DIF test related to skin biopsy?
Direct Immunofluorescence: Staining cells with antibodies directly linked to fluorochromes is known as direct immunofluorescence (DIF). Multiple antibodies may be detected on one sample.
What is SSA blood test?
SSA blood test is a type of blood test that is used to detect the presence of antibodies known as anti-Ro/SSA antibodies. These antibodies are associated with autoimmune conditions such as Sjögren's syndrome and systemic lupus erythematosus. The test is typically used to help diagnose and monitor these conditions.
