What Is Ca19 9 Blood Test

What Is The Ca199

Dr. Ma on the Utility of the CA 19-9 Test in Patients With Pancreatic Cancer

CA 19.9 is a cancer antigen that exists on the surface of cancer-causing cells. The levels of CA 19.9 are elevated highly during pancreatic cancer. CA 19.9 can be measured in the blood. Testing of the levels of CA 19.9 is useful as a tumor marker. The CA 19.9 level elevates especially during pancreatic cancer. The levels of CA 19.9 can, however, be elevated in the conditions of other cancers like Ovarian cancer, lung cancer, liver cancer, cholangiocarcinoma, gastric cancers, etc.

What Is It Used For

A CA-125 blood test may be used:

  • To see if ovarian cancer treatment is working and to check for ovarian cancer that has come back. This is the most common use of CA-125 blood testing.
  • To learn more about a growth or lump in your pelvis . If a suspicious lump shows up on imaging, such as an ultrasound, your health care provider may check your CA-125 levels along with other tests to find out whether the lump could be ovarian cancer. But a CA-125 blood test alone can’t diagnose cancer.
  • To screen for ovarian cancer if you’re risk is very high. If your family health history includes ovarian cancer, your provider may suggest a CA-125 blood test and other tests to look for signs of cancer. But a CA-125 test is not used as a routine screening test for people who don’t have a high risk for ovarian cancer. That’s because many common conditions that aren’t cancer can also cause high CA-125 levels, such as endometriosis or even a menstrual period.

What Is The Procedure Of The Sweat Chloride Collection For The Ca 199 Test

The sweat chloride sample might be collected for the CA 19.9 test to be conducted. The procedure of the collection of the sweat chloride sample involves the following steps: The patients skin is washed and dried. A pad soaked in pilocarpine is placed on the skin. A mild current is created by the electrode. This helps in moving the chemicals in the skin where the sweat glands are located. The stimulated area starts to sweat. The pad and the electrodes are removed. A piece of filter paper is placed over the area. The filter paper is weighed before placing it on the spot. This area is completely covered with plastic and tightly bandaged. Sweat is collected for 30 minutes. The sweat is collected in the filter paper. This filter paper is again weighed. It is then placed into a buffer to evaluate the concentration of the chloride. For similar procedures, sweat can also get collected into a plastic coil of tubing or onto a piece of gauze. The sweat sample hence collected is then sent for further tests.

What Factors Affect Blood Sugar

You can guess that carbohydrate intake and insulin production are at least partly responsible for your blood sugar levels. But the list is much longer — almost every lifestyle choice you make can affect your blood sugar. Here’s just a partial list.

  • Exercise can affect insulin sensitivity, leading to lower blood sugar for up to 48 hours.
  • Alcohol intake increases insulin production, causing low blood sugar.
  • Stress hormones like cortisol can raise blood sugar, because your body wants access to energy in order to escape what it perceives as a dangerous situation.
  • Medications, especially statins and diuretics, can raise blood sugar. Statins are used to treat cholesterol, and diuretics for high blood pressure.
  • Diet is a major player in blood sugar. Eating too many simple carbs at once can cause levels to skyrocket, while protein intake leads to a slower increase in blood sugar.
  • Dehydration raises blood sugar, because with less water in your body the glucose concentration will be higher.

Other surprising factors can affect your blood sugar, like a sunburn or gum disease, so if you’re dealing with a blood sugar issue and can’t figure out what’s causing your spikes and dips, talk to a healthcare professional.

What Is Ca 19

Antigens are substances that cause the immune system to respond. Carbohydrate antigen 19-9 is a type of antigen released by pancreatic cancer cells. It can also be referred to as a tumor marker.

The CA 19-9 Radioimmunoassay is a blood test that measures the CA 19-9 level in the blood.

There are blood tests commercially available that may be able to detect pancreatic cancer. A test measuring CA 19-9 cannot detect the presence of pancreatic cancer by itself, but it can be used on a panel with other biomarkers that can signal the presence of the disease. After diagnosis, the CA 19-9 Radioimmunoassay blood test can also be used for some patients to watch the diseases development.


  • Not every patient with pancreatic cancer will have a high CA 19-9 level.
  • Some conditions other than cancer can cause high CA 19-9 levels.
  • The CA 19-9 test cannot be used to diagnose or screen for pancreatic cancer by itself. Instead, doctors often use it to judge a treatments success.

What Other Conditions Can Cause Elevated Ca 19

A high CA 19-9 is usually related to pancreatic cancer. But other cancers, like colorectal, lung and gallbladder cancers, can also cause raised levels.

Non-cancerous conditions that can cause high CA 19-9 levels include:

  • Blockage of the bile duct
  • Cystic fibrosis

During radiation therapy, CA 19-9 levels might be raised as dying cancer cells release CA 19-9. For this reason, the test is not usually done while the patient receives radiation treatment.

What Is The Procedure Of The Urine Test For The Ca 199 Test

In the case of the urine test, the samples of urine have to be collected over the time period of 24 hours. You will be given the containers from the diagnostic center in which you have to store your urine sample. You will be given instructions about the storage of the samples. Then itll be sent for the CA 19.9 test. The urine sample collection an be done in the following ways: It is necessary to empty your bladder right in the morning by excretion. Note the time. In the next 24 hours, you have to store all the urine passed in the container provided to you. Store the urine sample as per the guidelines. Generally, it is suggested to be kept in a refrigerator. Return the container to the diagnostic center. The sample will go for the CA 19.9 test.

Are There Any Risks To The Test

There is very little risk to having a CEA blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.

CEA tests of body fluids are usually very safe. Serious problems are rare. But you may experience one or more of the following side effects:

  • If you had a CSF test, you may feel some pain or tenderness in your back at the site where the needle was inserted. Some people get a headache after the test. This is called a post-lumbar headache.
  • If you had a peritoneal fluid test, you may feel a little dizzy or lightheaded after the procedure. There is a small risk of damage to the bowel or bladder, which may cause an infection.
  • If you had a pleural fluid test, there is a small risk of lung damage, infection, or blood loss.

How Can I Tell If My Blood Sugar Is Irregular

Again, only a doctor can diagnose a problem with your blood sugar. But you may be wondering how to know if it’s something you should get checked out. There can be two main issues with your blood sugar — either it’s consistently too high or too low. Even if you don’t have diabetes, there are some signs that your blood sugar levels are not functioning normally.

Hypoglycemia is a condition in which your blood sugar is too low. Signs include an irregular heartbeat, fatigue, shakiness and tingling or numbness in your face. If you consistently feel this way when you get hungry or between meals, talk to your health care provider.

On the flip side, hyperglycemia happens when your blood sugar is too high, and can happen to nondiabetics. Symptoms include frequent urination, increased thirst and headache. If you think you’re hyperglycemic and can’t keep fluids or food down, call for emergency medical assistance.

How Much Does The Test Cost

The cost of CA 19-9 testing depends on a variety of factors, such as a patients health insurance coverage, where the test is performed, and any additional testing that is conducted at the same time. Total costs may include those associated with obtaining and analyzing the test sample as well as charges for an office visit.

CA 19-9 testing may be covered by health insurance. It could help to contact the health insurance provider or the hospital or laboratory conducting the test for more information about out-of-pocket costs, such as copays or deductibles.

For patients without health insurance, or for whom insurance doesnt cover the cost of testing, a doctor or hospital administration can further discuss the out-of-pocket cost of CA 19-9 testing.

What Happens During A Cea Test

CEA is usually measured in the blood. During a CEA blood test, a health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.

Sometimes, CEA is tested in the spinal fluid or from fluid in the abdominal wall. For these tests, your provider will remove a small sample of fluid using a thin needle and/or syringe. The following fluids may be tested:

  • Cerebrospinal fluid , a clear, colorless liquid found in the spinal cord
  • Peritoneal fluid, a fluid that lines your abdominal wall
  • Pleural fluid, a liquid inside your chest cavity that covers the outside of each lung

What Is A Ca


This test measures the amount of a protein called CA-125 in a sample of your blood. CA-125 is a type of tumor marker. High levels of certain tumor markers in your blood may be a sign of cancer. If you have cancer, measuring certain tumor markers may help provide important information about how to treat your disease.

High levels of CA-125 are often found in people who have ovarian cancer. The ovaries are a pair of female reproductive glands that store ova and make female hormones. Ovarian cancer happens when the cells in an ovary begin to grow out of control.

If you have ovarian cancer, CA-125 blood tests can help show whether your treatment is working.

Other names: cancer antigen 125, glycoprotein antigen, ovarian cancer antigen, CA-125 tumor marker

How Often Is The Test Given

The doctor decides how often the CA 19-9 tests are performed. If the tumor seems to be growing during treatment, the CA 19-9 test may be repeated weekly or after each round of treatment is completed.

If a patient is not receiving treatment now, the CA 19-9 test may be used occasionally to decide if that patient should restart treatment or have more testing. People who had surgery might have CA 19-9 tests as part of their follow-up care.

When Is The Ca 19

Levels of CA 19-9 may be measured as part of a panel of biomarkers to detect the disease early from a blood test. Patients may also get the test after a confirmed pancreatic cancer diagnosis. If the CA 19-9 level was raised before treatment, patients may be tested during and after treatment to judge success.

CEA stands for carcinoembryonic antigen. It is a protein found in the tissues of a developing baby. CEA levels normally become very low or disappear after birth. Healthy adults should have very little or no CEA in their body.

This test measures the amount of CEA in the blood, and sometimes in other body fluids. CEA is a type of tumor marker. Tumor markers are substances made by cancer cells or by normal cells in response to cancer in the body.

A high level of CEA can be a sign of certain types of cancers. These include cancers of the colon and rectum, prostate, ovary, lung, thyroid, or liver. High CEA levels may also be a sign of some noncancerous conditions, such as cirrhosis, noncancerous breast disease, and emphysema.

A CEA test can’t tell you what kind of cancer you have, or even whether you have cancer. So the test is not used for cancer screening or diagnosis. But if you’ve already been diagnosed with cancer, a CEA test can help monitor the effectiveness of your treatment and/or help find out if the disease has spread to other parts of your body.

Other names: CEA assay, CEA blood test, carcinoembryonic antigen test

What Are The Risks Associated With The Collection Of The Synovial Fluid

There are a few common risks associated with the collection procedure of the synovial fluid. Some of these risks are listed below: Experiencing pain in the places of punctures Bruising and bleeding The medicine which is injected into the joint can cause various allergic reactions. The cartilages might get damaged inside the joint.

What Is The Procedure Of The Collection Of The Pleural Fluid For The Ca 199 Test

The pleural region is the space between the outside lining of the lungs and the chest wall. The fluid is collected from this space and is known as the pleural fluid. The procedure is called Thoracentesis which is used for the pleural fluid collection. The procedure of the pleural fluid collection is as follows: You will be instructed to sit on a bed or on the edge of a chair and rest your head and arms on a table. The area is detected from where the needle will be inserted. A numbing cream is applied. A local or general anesthesia is applied for numbing the particular area of the puncture. A hollow needle guided by the ultrasound is inserted in the pleural space. It is highly suggested not to cough, breathe heavily or move at all during the test procedure. This is to avoid any injury or bruising. The fluid is drawn inside the tube of the syringe. After the collection of the pleural sample, the area is cleaned and bandaged. The pleural fluid is then sent to the laboratory for the CA 19.9 test.

The Importance Of The Ca 19

Cancer Antigen 19.9 Test

The protein CA 19-9 is a tumor marker often used by doctors to confirm a pancreatic cancer diagnosis or monitor a patients progress through treatment. Unfortunately, test results arent always clear-cut: CA 19-9 levels can rise with noncancerous conditions, like pancreatitis, and with other cancers. While 90 percent of us produce CA 19-9 normally, ten percent of us dontand therefore wouldnt test for elevated levels even in the presence of pancreatic cancer. For those reasons and others, the marker isnt sensitive enough to rely on for screening.

But the implications of elevated CA 19-9 levels may be much further-reaching than doctors once thought, says , a gastrointestinal surgical oncologist at Mayo and the lead author on a provocative paper presented last November at the Western Surgical Association annual meeting in Napa, Calif. and published this winter in the Journal of the American College of Surgeons.

Using the National Cancer Database, Truty and his team retrospectively looked at the cases of 113,145 pancreatic cancer patients and found that only 25% received a CA 19-9 blood test at diagnosis, independent of their cancer stage.

More strikingly, Truty and his colleagues also observed that patients with elevated CA 19-9 levels had significantly worse survival outcomes than patients at the same cancer stage whose levels were lower.
