As a nurse, I’ve seen too many patients become overwhelmed or even anxious when they see an elevated lab result. It’s also easy for them to overlook important numbers because they don’t understand them.
Maybe you just remember your clinician saying your “numbers look good,” but you don’t know what they tested or what the results actually were.
You’ll find lots of numbers in your medical chart, but you don’t need to memorize each one. However, knowledge is power when it comes to advocating for your health. Here, we’ll look at 18 health numbers every woman over 50 should have memorized.
What These Health Numbers Actually Mean
You should know that different labs can use different reference ranges, a single abnormal result doesn’t give you a diagnosis, and trends within the clinical context matter.
A lab result outside the normal range doesn’t automatically mean something is wrong. On the other hand, a “normal” result doesn’t always mean your health is on the right track. How your results trend over time can paint a better picture than a single result.
A lab value is only a small part of your larger health puzzle. The other pieces are your health history, medications, symptoms, and other test results. Putting them all together helps your clinician identify a diagnosis and create a health plan.
Blood Test Numbers Women Over 50 Should Know
Here are a few lab numbers worth knowing. Keep in mind that they should still be interpreted with your health history, symptoms, and overall risk. For a deeper look at which blood tests may matter after 50, see my guide to annual blood tests for women over 50.
1. LDL Cholesterol
Your cholesterol test may result in a few different numbers. An important one to know is your LDL cholesterol, also known as low-density lipoprotein. It’s often referred to as “bad cholesterol” because too much of it in your blood can form hard deposits called plaque.
According to the American Heart Association (AHA), a goal LDL level depends on your overall cardiovascular risk. For some people, an LDL below 100 mg/dL is ideal. For others, it may be even lower if they’re at a higher risk for cardiovascular disease.
Talk with your clinician about your overall risk and not just your LDL result. The important thing to know is that high cholesterol can be managed with diet, lifestyle changes, and/or medications if needed.
2. A1C
An A1C test measures your average blood sugar level over the past 2 to 3 months. It gives clinicians an idea of how your blood glucose has been running over time.
The American Diabetes Association (ADA) says a normal A1C result is below 5.7%. Prediabetes falls between 5.7% and 6.4%. If your A1C level is 6.5% or higher, it may mean you have diabetes, and your clinician will likely repeat the test to confirm.
This number matters because your risk for type 2 diabetes increases with age. Menopausal changes in the body can also affect how well your body responds to insulin.
3. Fasting Blood Glucose
Fasting blood glucose is similar to A1C, but it measures your blood sugar in real time after you haven’t eaten for at least 8 hours. It tells clinicians what your blood sugar level is at the time of the test.
The ADA defines a normal fasting glucose as 99 mg/dL or lower. A possible sign of prediabetes is a result from 100 to 125 mg/dL, while diabetes is 126 mg/dL or higher.
4. TSH
TSH stands for thyroid-stimulating hormone and is released by the pituitary gland. Clinicians use it to check how well your thyroid gland is functioning.
The American Thyroid Association notes that many labs use a normal TSH range around 0.4 to 4.0 mIU/L, although the exact range can vary. A low level may mean your thyroid is overactive, while a high level usually suggests an underactive thyroid.
Thyroid issues are more common with age. The symptoms may also overlap with menopause or normal aging.
5. eGFR
Your eGFR is your estimated glomerular filtration rate. It gives insight into how well your kidneys are functioning.
It’s only an estimate, but the National Kidney Foundation puts the expected range at 60 mL/min/1.73 m2 or higher . However, your age and other factors also matter.
That’s why this number is important. Kidney function may decline with age. Other conditions, like high blood pressure and diabetes, may also affect kidney function. But one low result doesn’t mean you have chronic kidney disease.
Health Numbers Your Clinician Measures at a Visit
Your clinician looks at more than lab results. These numbers are also useful when tracked over time.
6. Blood Pressure
The AHA says a normal blood pressure is less than 120/80 mm Hg. A systolic reading of 120 to 129 with a diastolic below 80 is considered elevated. Hypertension starts at 130 systolic or 80 diastolic. Severe hypertension is a systolic higher than 180 and/or a diastolic higher than 120.
Blood pressure tends to rise with age. It’s also easily missed since it often doesn’t cause symptoms. A single office reading doesn’t mean you have hypertension. Your clinician may monitor it over time or ask you to check it at home.
7. Resting Heart Rate
Your resting heart rate is how many times your heart beats per minute while at rest. Even though many factors can affect your heart rate, the common adult range is 60 to 100 beats per minute.
Changes from your usual baseline may need further evaluation, especially with dizziness, fainting, chest pain, or shortness of breath.
8. Waist Circumference
Waist circumference is the distance around your waist, but they’re not measuring you for pants. It matters because more abdominal fat is linked with a higher risk for type 2 diabetes and cardiovascular disease.
The National Heart, Lung, and Blood Institute notes that, in women, a waist circumference of 35 inches or more may indicate a higher health risk. As women age, fat distribution often shifts toward the abdomen.
However, a high number isn’t a diagnosis. Your clinician can use it as one risk marker when assessing your overall health.
9. BMI
Body Mass Index (BMI) is a measure of your weight in relation to your height. It doesn’t take into account your muscle mass, bone density, or overall body composition.
After 50, a woman’s body composition can change, so a single BMI reading may not tell the whole story.
The Centers for Disease Control and Prevention (CDC) states that a healthy BMI range for adults is 18.5 to less than 25. A BMI from 25 to less than 30 is categorized as overweight, while 30 or greater falls into the obesity category. A BMI below 18.5 is categorized as underweight.
10. Bone Density T-Score
The Bone Health and Osteoporosis Foundation notes that women can lose up to 20% of their bone density in the five to seven years after menopause. That’s why your clinician may order a bone mineral density test to check for osteoporosis.
The test results in a T-score. A T-score of -1.0 or higher is considered normal. A result between -1.0 and -2.5 indicates low bone mass, also called osteopenia. A T-score of -2.5 or lower is considered osteoporosis.
11. Weight Change
An unexpected weight change can tell clinicians more than the measurement itself.
A sudden drop in weight matters because it may be an early warning sign of a health condition. Tell your clinician if you’ve lost more than 5% of your body weight within 6 months without trying through diet or exercise.
Unintentional weight loss may be caused by illness, medication changes, appetite changes, mental health conditions, or trouble absorbing nutrients.
Health Numbers You Can Track at Home
12. Hours of Sleep
Women over 50 need the same amount of sleep as other adults. The National Institute on Aging puts the recommended amount at 7 to 9 hours each night.
Not getting a good night’s rest can affect your mood, blood pressure, blood sugar, and even your memory. Menopause symptoms like night sweats can also interfere with your sleep.
The number of hours matters, but the quality of sleep is also important. If you’re experiencing persistent sleep problems, make sure to let your clinician know.
13. Resting Breathing Rate
The name says it all. Your resting breathing rate is how many breaths you take in one minute while at rest.
The American Lung Association puts the normal resting adult range at 12 to 20 breaths per minute. Any shift from your usual range can be a sign of illness, pain, anxiety, or another condition.
Talk to your clinician if your rate stays unusually high or low, especially with shortness of breath, chest pain, confusion, or bluish-colored lips.
14. 30-Second Sit-to-Stand Count
The next number may be new to you. A 30-second sit-to-stand count can show how well your lower body functions and how strong it is.
You test it by counting how many times you can stand up from a chair and sit back down in 30 seconds. To ensure accurate results, make sure you’re doing the test the same way each time. Technique matters.
As you age, leg strength affects your mobility, independence, and fall risk. According to the CDC, fewer than 12 repetitions is considered below average for women ages 60 to 64. For women ages 65 to 69, fewer than 11 is below average.
A low score isn’t enough to make a definitive conclusion on your health. Instead, think of it as a reason to speak with your clinician or physical therapist.
15. Single-Leg Balance Time
Your body’s ability to balance changes with age. This measurement is done by timing how long you can stand on one leg without holding onto something.
A 2026 study in GeroScience found, for women ages 50-54 performing single-leg stance with eyes closed, a median of about 6.1 seconds, with a wide range. However, many factors impact balance besides age. People also rely on vision, inner-ear function, and their nervous system to help maintain stability.
If you’re suddenly finding yourself unable to balance as well, it’s a good idea to notify your clinician.
16. Usual Walking Speed
As you’re walking your dog or pacing around the store, notice how fast you normally walk at a comfortable pace. That speed matters to women over 50 because it can reflect strength, balance, mobility, and overall function.
The same GeroScience data put the median walking speed for women ages 60 to 64 at about 1.03 meters per second.
Age and overall health play a role. A slower pace over time can tell you more than one isolated measurement. If you suddenly have trouble walking or experience dizziness, pain, or shortness of breath, it’s worth discussing with your clinician.
17. Weekly Physical Activity Minutes
The CDC recommends at least 150 minutes of moderate-intensity aerobic exercise each week. Strength training is also recommended a couple of times a week to help build muscle and strengthen bones.
After 50, women benefit from regular exercise because it supports heart health, mobility, and independence. If you’re inactive now, you can take it slow and build up to the 150-minute goal.
18. Falls in the Past Year
Think about how many times you’ve fallen in the past year. The CDC considers a history of falls an important part of assessing your fall risk.
After 50, things like balance, strength, vision, and medications can all contribute to your overall risk for falls.
Be sure to count every fall, even if there’s no injury. Any fall or new problems with balance are worth mentioning to your clinician.
The 4 Health Numbers Worth Knowing Cold
Out of all the numbers we discussed, these four are worth knowing after 50: blood pressure, A1C, LDL cholesterol, and bone density T-score.
You don’t need to memorize everything. Instead, you want to leave each medical office visit knowing that these four were reviewed by your clinician and discussed.
These four numbers can help indicate your risk for diabetes, cardiovascular disease, and osteoporosis.
However, these numbers are most useful when tracked and trended over time. A single result isn’t enough to judge your overall health.
What to Ask About Your Numbers at Your Next Appointment
Your clinic visit should be a two-way conversation about your health. It’s acceptable to question your clinician’s decisions and to ask which of these numbers were checked today. If not, why?
You should also know the actual results of your labs and tests, not just that they were “normal.” How the results compare with your past results matters. You also want to know whether the labs are normal based on the general reference range or if they’re “normal for you.”
Finally, ask what you should be doing at home. Should you be monitoring anything between visits? Is there any reason you should follow up with them sooner?
When an Abnormal Health Number Needs Faster Attention
An abnormal health number may need faster attention, especially if you’re experiencing other symptoms. Listen to your body.
For example, if your blood pressure is high, are you also experiencing shortness of breath or chest pain? A major change in breathing with confusion or skin color changes may be a sign that you’re not getting enough oxygen.
Keep in mind that some abnormal numbers don’t always need immediate follow-up. For example, a low T-score or abnormal waist measurement may simply need to be monitored and discussed at your next routine follow-up.
The Bottom Line
The takeaway is to know the numbers most relevant to your health. Pay attention to trends instead of only an isolated result.
Think of these numbers as a tool. They can help you ask better questions during your clinician visits, but they aren’t something to panic over.
