Is Your Doctor Ordering These 7 Important Tests?

Are you regularly doing your CBCs and CMPs and checking your cholesterol levels? That’s great. And if you are feeling well and overall healthy, it’s likely enough. But what happens when all of these tests are coming back normal yet you still feel like something is wrong? It may be time to dig deeper. Here are some of the tests you and your doctor can easily incorporate into your regular check-ups that can tell you a lot more about your body and help reveal important issues and imbalances. What Blood Tests Should You Get?

We now have at our disposal more ways to tell what’s going on in our bodies than ever before. But oftentimes, these tests are not relied upon, especially when it comes to prevention.

For example, you may be testing your glucose , but not your insulin levels. You may be checking your iron , but not your ferritin. Your lab results may suggest everything is fine until things get seriously out of order. But the truth is – your body may be functioning suboptimally, and, with the right tests, your doctor can often tell.

Here are eight tests that are great to catch chronic diseases in their early stages. Discuss taking them with your doctor. One of these may just be a game-changer for you. Important Tests You May Not Be Getting

1) Insulin

Even if your blood sugar (glucose) levels are fine, your body may still be struggling to keep them in line. You will know if that’s the case when you check your insulin levels.

Insulin is a hormone that is released when you eat in order to help move glucose from the blood into the tissues (mainly muscles, fat tissue, and liver) [ 1 , 2 ]. Insulin levels can go out of balance long before blood sugar does (you can read more about insulin resistance here ).

Researchers found that having fasting insulin levels above the optimal range increases your risk of developing metabolic syndrome, diabetes, heart disease, and dementia [ 3 , 4 , 5 , 6 , 7 , 8 ]. For example, one study found that a fasting insulin level above 9.0 uIU/mL (well within the normal range of up to 25 uIU/mL) could identify prediabetes with 80% accuracy [ 5 ]. 2) Ferritin

You may be testing your iron levels, but are you checking your ferritin ? Even if your iron is within the normal range, low ferritin can indicate iron deficiency. And if you have unexplained fatigue and ferritin is on the lower side – that indicates you are deficient in iron.

Ferritin is an iron-storing protein. It is important for maintaining proper levels of iron and making sure that iron is available for the different bodily processes that need it. Essentially, ferritin is a measure of your body’s iron stores [ 9 ].

Low ferritin levels are usually due to some kind of gut inflammation that is not allowing the person to absorb iron well, or because of hypothyroidism . When iron (indicated by ferritin) is lower, it can worsen existing health problems. Studies suggest that low ferritin may increase the risk of depression and anxiety by about twofold [ 10 , 11 ].

Conversely, ferritin may be high in many chronic inflammatory conditions including metabolic syndrome, fatty liver, kidney disease, autoimmune disease, diabetes, and cancer [ 12 ]. This makes ferritin a marker of acute and chronic inflammation.

Here is an alarming statistic – research suggests that about half (48%) of the U.S. population is deficient in magnesium [ 13 ].

Why is this alarming? Magnesium is the 4th most abundant mineral in our bodies and it’s required for more than 300 different bodily processes [ 14 , 15 ]. A deficiency can wreak havoc on your health. When your magnesium levels are low, you may experience a loss of appetite, fatigue, nausea, insomnia , irritability, and muscle weakness.

In addition, the older you get, the less efficiently your body holds onto magnesium [ 16 , 17 , 18 ]. In its worst stages, magnesium deficiency can contribute to osteoporosis, heart disease, high blood pressure , and diabetes [ 19 , 20 , 21 , 22 , 15 , 14 , 23 ].

Thankfully, magnesium levels are very easy to test. If your levels are suboptimal or low, you can correct them by increasing your intake of magnesium-rich foods or supplementing. 4) hs-CRP

Another important marker to keep track of if you are concerned about your heart health is C-reactive protein (CRP). Doctors use it to help predict your risk of heart disease. One study suggests that when both CRP and cholesterol levels are high, it may increase the overall risk of heart disease up to ninefold [ 24 ]!

CRP is a protein that increases in response to chronic stress (lack of sleep , emotional issues, smoking, alcoholism, diabetes, nutritional deficiencies, etc.). It’s a great measure of chronic inflammation in your body. 5) LDL Particle Number and Size

Concerned about heart disease? You may be checking your cholesterol levels regularly (if you are not, you should be). But what about your LDL particle number?

LDL particles transport cholesterol in the bloodstream. You can think of LDL particles as cars on a highway (blood vessel) and cholesterol and fats like triglycerides as the passengers. A standard lipid panel will give you a measure of the number of passengers on the roads, but you need LDL particle number to know the number of cars. In addition, LDL particles come in different sizes, with large particles able to carry more cholesterol (buses and SUVs) than small particles (2-seaters) [ 25 ].

Why do LDL particle number and size matter?

For decades, reducing LDL cholesterol has been the primary target for doctors in treating and preventing heart disease. However, researchers found that almost 50% of people who have a heart attack have normal LDL cholesterol levels! In addition, in clinical trials with LDL cholesterol-reducing […]
