HealthCheckUSA Health Alert: Most Important Lab Tests Women Should Have

Category : blood tests, thyroid screenings, thyroid test


By Dr. Rwanda Campbell, August 6, 2009

1. A Pap Smear Test examines cells for any changes that may indicate the possibility of cervical cancer. Campbell recommended that the first test be conducted at the age of 20 or at the onset of sexual activity and continued annually until age 65 or 70. She said some insurance companies allow the test annually and others cover the test every three years if test results are normal. Even if the pap smear isn’t performed every year, Campbell said it is important for every woman to have an annual pelvic exam.

2. A cholesterol blood test is important because high cholesterol levels have no symptoms but can be deadly. Excess LDL, or bad cholesterol, can cause build-up in the arteries and interfere with blood flow. HDL, the good cholesterol, has protective qualities and can remove LDL from the blood. Some pediatricians now test cholesterol levels and Campbell said everyone should get a baseline test by the age of 20. The test should be repeated at least every five years until the age of 45. Anyone older than 45 with a family history of heart disease or high cholesterol levels should be screened annually. While medications are available to lower cholesterol levels, the physician said it is better to lower cholesterol through diet modification.

3. Breast exams are recommended at age 30 and every three years after that while mammograms are recommended annually beginning at age 40. A clinical breast exam checks breast tissue for lumps, thickening or other changes that warrant follow-up. Mammograms are X-rays of the breast tissue that may find cancers when they are still too small to be felt. Breast cancer is most curable if it is found in its earliest stages. Campbell said genetic testing is available to women whose mothers or sisters have had breast cancer.

4. Skin cancer screenings should begin by the age of 30 and be conducted annually thereafter. A primary care provider or dermatologist may do head-to-toe screenings. Skin cancer is the second most common cancer in women and is curable if it is caught early. Women with fair skin, repeated sunburns, many moles and a family history of skin cancer are have the highest risk of developing skin cancer.
5. Thyroid lab tests are needed to make sure the gland is functioning properly. The thyroid gland regulates the way the body uses energy. If the thyroid gland is overactive, it may lead to rapid weight loss and nervousness. If it isn’t up to speed, a person may feel weak, fatigued, generally unwell, depressed and suffer from excessive vaginal bleeding. Early diagnosis can avoid more debilitating conditions like heart disease, high cholesterol and stroke, she said. Screenings should begin at the age of 35 and continue every five years, or more often if the woman experiences thyroid symptoms or has risk factors, such as a family history of thyroid problems. Thyroid problems may be adjusted with medication.

6. Blood pressure levels are checked every time a person visits a doctor. High blood pressure levels can lead to heart attack, stroke, heart failure and kidney damage. High levels produce no symptoms. Campbell said high blood pressure is often weight related for women. Blood pressure readings should be below 140/90. High blood pressure, or hypertension, may be treated with lifestyle changes and/or medication.

7. Diabetes is a condition in which the body doesn’t make enough insulin or has a reduced response to insulin. It will cause blood sugar levels to be too high and increase the person’s risk of heart disease and stroke. It can also result in birth defects during pregnancy and premature menopause. Screening guidelines call for testing by the age of 45 or sooner if risk factors are present. Campbell recommended screenings before that and for any woman who is overweight.

8. Colonoscopies examine the large intestine for signs of colon cancer, which is 90 percent curable if found early. Growths and polyps may be removed and biopsied during the test. Preparation for the test (a bowel cleansing) is a bigger challenge than the test itself because patients are usually asleep during the procedure, the physician said. The first screening is usually done when the patient turns 50 and is repeated every 10 years if no polyps or risk factors exist. Higher-risk patients, such as those with a family history of colon cancer, should get their first test 10 years before the family member was first diagnosed and every five years after that.

9. Bone-density scans measure the mass of a patient’s bones and assess her risk of developing osteoporosis. Campbell said a broken hip could be a life-changing event; it can mean moving to a nursing home. Weight-bearing exercise, Vitamin D and calcium help build bone mass in younger patients, but medicines may be needed in older patients. Women may lose up to 20 percent of their bone density in the five to seven years after menopause. Campbell recommended women have their first bone-density screenings by age 65 and that they be repeated every five years. Doctors may suggest testing at an earlier age for patients who are underweight, have ever smoked, have a recent history of broken bones or a family member with osteoporosis.

10. Hormone Blood Tests that Assess your menstrual cycle is the last test for women and one that directly affects quality of life for many women. Campbell said she encounters patients who live in fear of having menstrual accidents and who won’t leave home because their flow is too heavy. “That is not normal,” she said. “There are many options available for women today.” Medications and ablation may both reduce the severity and length of periods. Hysterectomies, which used to be the only option, are now considered options of last resort.

Definition of a Cholesterol Blood Test
A complete cholesterol blood test — also called a lipid panel or lipid profile — is a group of blood tests that can measure the amount of cholesterol and triglycerides in your blood. A cholesterol blood test can help determine your risk of atherosclerosis, the buildup of plaques in your arteries that can lead to narrowed or blocked arteries throughout your body. If your cholesterol levels are high, you probably won’t have any signs or symptoms, so a cholesterol blood test is an important tool. High cholesterol levels are a significant risk factor for heart disease.

Why a Cholesterol Blood Test is Done
Cholesterol and triglycerides are substances that naturally circulate in your blood. Although these substances are necessary for your body to function normally, too much fat in your blood increases your risk of heart disease, a stroke, or narrowed arteries in your arms or legs (peripheral artery disease).

What’s Measured in a Cholesterol Blood Test?
A complete cholesterol blood test, referred to as a lipid panel or lipid profile, includes the measurement of four types of fats (lipids) in your blood:

  • Total cholesterol. This is a sum of your blood’s cholesterol content.
  • High-density lipoprotein (HDL) cholesterol. This is sometimes called the “good” cholesterol because it helps carry away LDL cholesterol, thus keeping arteries open and your blood flowing more freely.
  • Low-density lipoprotein (LDL) cholesterol. This is sometimes called the “bad” cholesterol. Too much of it in your blood causes the buildup of fatty deposits (plaques) in your arteries (atherosclerosis), which reduces blood flow. These plaques sometimes rupture and can lead to a heart attack or stroke.
  • Triglycerides. Triglycerides are a type of fat in the blood. When you eat, your body converts any calories it doesn’t need to use right away into triglycerides, which are stored in fat cells. High triglyceride levels usually mean you regularly eat more calories than you burn. High levels are also seen in overweight people, in those consuming too many sweets or too much alcohol, and in people with diabetes who have elevated blood sugar levels.

Who should get a cholesterol test?
All adults age 20 or older should have a cholesterol test once every five years. Ideally, you should begin having your cholesterol checked in your early twenties. You should have your cholesterol measured when you’re relatively healthy. An acute illness, a heart attack or severe stress can affect cholesterol levels.

Cholesterol blood testing is very important if you:

  • Have a family history of high cholesterol or heart disease
  • Are overweight
  • Are physically inactive
  • Have diabetes
  • Eat a high-fat diet

These factors put you at increased risk of developing high cholesterol and heart disease.

If you have high cholesterol levels, your doctor may want you to get your blood tested more often. Discuss with your doctor how often you should have a cholesterol blood test if your cholesterol levels are abnormal.

Cholesterol is often high during pregnancy, so pregnant women should wait at least six weeks after giving birth to have their cholesterol measured.

Children and Cholesterol Blood Testing
Children as young as age 2 can have high cholesterol, but not all children need to be screened for high cholesterol. The American Academy of Pediatrics recommends a cholesterol blood test only for children between the ages of 2 and 10 who have a known family history of high cholesterol or premature coronary artery disease. Your child’s doctor may recommend retesting if your child’s first test shows he or she has normal cholesterol levels.

The American Academy of Pediatrics also recommends testing if the child’s family history for high cholesterol is unknown, but the child has risk factors for high cholesterol, such as obesity, high blood pressure or diabetes.

Risks of getting a Cholesterol Blood Test
There’s little risk in getting a cholesterol blood test. You may have some soreness or tenderness around the site where your blood is drawn, or the site may become infected.

How you prepare for your Cholesterol Blood Test
You should fast (no food or liquids other than water) for nine to 12 hours before the test. You can drink water in the time leading up to the blood test, but avoid coffee, tea and other beverages.

Talk to your doctor about any other special requirements. Some medications, such as birth control pills, can increase your cholesterol levels. For this reason, if you take these or other medications, your doctor might want you to stop taking them for a few days before your cholesterol blood test.

What you can expect from your Cholesterol Blood Test
During the procedure
A cholesterol test is a blood test, usually done in the morning since you’ll need to fast for the most accurate results. Blood is drawn from a vein, usually from your arm. Before the needle is inserted, the puncture site is cleaned with antiseptic and an elastic band is wrapped around your upper arm. This causes the veins in your arm to fill with blood.

After the needle is inserted, a small amount of blood is collected into a vial or syringe. The band is then removed to restore circulation, and blood continues to flow into the vial. Once enough blood is collected, the needle is removed and the puncture site is covered with a pressure wrap.

The entire procedure will likely last a couple of minutes. It’s relatively painless.

After the procedure
There are no special precautions you need to take after your cholesterol blood test. You should be able to drive yourself home and do all your normal activities. You may want to bring a snack to eat after your cholesterol test is done, if you’ve been fasting.

It may take a few days for you to get your results back. Your doctor should explain to you what the results of your test mean. It’s likely your doctor will want to retest you in several weeks or months if your test shows your cholesterol levels are high. Before starting any treatment based only on an abnormal cholesterol test, it’s common to get several tests done over a period of time to ensure an accurate diagnosis.

Cholesterol Blood Test Results
In the United States, cholesterol levels are measured in milligrams (mg) of cholesterol per deciliter (dL) of blood. In Canada and many European countries, cholesterol levels are measured in millimoles per liter (mmol/L).

The four main categories — total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides — are what are most commonly measured during a cholesterol blood test. Still, many doctors have begun examining other substances in the blood. Tests of these other substances in the blood are often done on the same sample of blood taken during a cholesterol test and meant to complement, not replace, a standard lipid blood panel or lipid blood profile cholesterol blood test.

If your results show that your cholesterol level is high, don’t get discouraged. You may be able to lower your cholesterol with lifestyle changes, such as quitting smoking, exercising and eating a healthy diet. If lifestyle changes aren’t enough, cholesterol-lowering medications also may help. Talk to your doctor about the best way for you to lower your cholesterol.

Women and cholesterol test results
The hormone estrogen tends to cause women to have higher levels of HDL, “good,” cholesterol but also higher levels of triglycerides. If you have higher levels of triglycerides than normal, talk to your doctor. Many women who are at risk of heart disease and have high cholesterol or triglyceride levels may benefit from cholesterol-lowering medications.
