PART 1
According to the World Health Organization, chronic diseases kill millions of people each year. Diabetes alone accounted for nearly 1.6 million deaths in 2015. Deaths caused by neurodegenerative diseases such as dementia doubled since 2000, and this number is expected to grow in the upcoming years. Although these are alarming facts, you might be happy to find out that numerous diseases and injuries, particularly chronic illnesses, can be prevented. To prevent a disease, you first need to be aware of it. To be aware of it, you need to do the right thing and get your health checked periodically. Discovering a predisposition to the disease earlier on gives you a massive advantage. You’ll be able to follow special treatments and minimize its risks or eliminate them. But how to get tested for various diseases which might affect you? Well, one of the simplest and most efficient ways is to go to some good lab and have your health profile test done at affordable prices and have your general health checked in a matter of days. No doctor visit is required so that you can quickly check your blood tests and monitor your health if you are an educated patient. However, you need to keep in mind that there are many factors which can influence the results of your lab tests. In other words, these factors can reduce the accuracy of your results, and that’s why you need to follow up the doctor’s advice before drawing blood for testing.
- Biotin
Biotin is also known as vitamin B7 or vitamin H. This is a coenzyme the body needs for different metabolic processes. For example, the body needs biotin to optimize the metabolism of fat, carbohydrates, and protein. At the same time, biotin is also needed for the production of certain hormones. You can find biotin in fish, eggs, meat and certain vegetables such as spinach and broccoli. However, you can also take biotin supplements if needed. Adults need about 30 micrograms of biotin per day. Having more biotin in your system is not a problem, but it might affect some lab tests you make. For example, it can interfere with the results in certain blood tests, which might lead to an incorrect diagnosis of various health ailments.
Biotin Uses and Supplementation
As mentioned earlier, biotin is present in various pills and supplements. For example, biotin can be used for treating alopecia, which is a health condition that makes people lose their hair. Doctors prescribe a dose of 5,000 to 10,000 micrograms of biotin per day to treat such health problems. At the same time, biotin can also be prescribed to pregnant women to support the healthy development of the baby. There are studies performed by researchers at various universities which prescribe large biotin doses to treat various problems with the nervous system. For example, multiple sclerosis might be treated with around 300,000 micrograms of biotin per day. Some people also use biotin to treat nail and skin problems since no studies are suggesting that a high amount of biotin can lead to health complications or injuries.
How Biotin Affects Test Results
Although supplementing with biotin can be beneficial for the body, this substance can greatly interfere with test results. The FDA (Food and Drug Administration) mentioned that biotin could alter blood test results and cause incorrect diagnosis for certain health conditions.It is recommended that you stop biotin supplementation at least 72 hours before offering a blood or saliva sample.
What Are the Lab Tests Which Might Be Affected by Biotin Supplementation?
There are many blood tests which can be affected by excessive biotin levels in your bloodstream. Some of these tests include vitamin D tests, any tests which measure the thyroid hormones in your body as well as tests which look at the FSH and LH hormones. Troponin is another type of test commonly used to diagnose heart attacks and other problems related to the cardiovascular system. If you’re planning to do such blood tests in the future, make sure you put your biotin supplementation on hold to ensure you get accurate results.
- Age
The advancing age of a patient also significantly influences the results of a particular blood test. In most cases, people of an elderly age tend to receive a higher percentage of incorrect/inaccurate results in comparison with younger adults. That’s because certain hormones and substances in the body are interpreted differently by lab tests as their levels increase or decrease with age. To give you an accurate example, a lipid panel of an older adult is much different than the one of a young person. The levels of triglycerides, good cholesterol, and bad cholesterol tend to increase with age up to about 55-60 years in males and around 65 years in females. Some studies show that triglyceride levels continue to increase in senior females. When this happens, doctors don’t use reference values based on age anymore because they are inefficient in people of elderly age. Instead, they test the risk of cardiovascular disease and formulate treatment options based on that because this method is much more efficient. At the same time, there are blood tests which measure the prostate-specific antigen (PSA) levels in men. PSA can increase in people of an elderly age as more PSA gets into the bloodstream and interferes with the test results.
- Urinary Tract Infection
Another factor that can influence the results of a PSA test consists of urinary tract infections. Various urinary tract bacteria can drastically alter the test results and lead to inaccurate diagnosis. That’s why it’s a good idea to tell your doctor if you ever had urinary tract infections so he can make a more accurate diagnosis when testing your PSA levels.
- Prostate Procedures
People who have had prostate procedures done are more likely to receive an incorrect diagnosis when doing prostate tests. For example, prostate surgery or biopsy, as well as prostatitis, can cause abnormal levels of PSA in the body. These factors can interfere with test results and cause false diagnosis. The doctor will eventually inform you when it’s a good time to have a prostate test after you have had done a prostate surgery or biopsy.
- Bicycle Riding
Some studies have found that riding a bicycle can put a lot of pressure on the prostate, which can increase PSA levels. Therefore, prostate test results can come back with incorrect information, which leads to a false diagnosis. Another thing that can increase PSA levels is ejaculation since it makes more PSA leak into the bloodstream and affects the test results.
- Obesity or High Body Weight
Obesity is another health issue that affects the results of various blood tests. For example, obese men have greater BMI, and they usually have lower PSA concentrations. That’s because obese men usually have a larger blood volume where PSA can get diluted. As a result, a prostate test can return false PSA results which affect the diagnosis set by the doctor. Similarly, obesity can also affect the results of rheumatoid arthritis tests. During those tests, various inflammatory markers such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR) are checked to detect the level of inflammation in the body. Some studies show that obese people tend to have higher levels of ESR and CRP in their bodies, and this can interfere with the results, leading to false diagnosis. Another blood test that can be affected by body weight is creatinine (used to assess kidney function). This test result may be artificially elevated in people with higher body weight or lean mass. Cystatin C may be a better indicator of kidney function in those patients.
- Medications
Any medication that you might take before doing a blood test can significantly influence the results. Make sure that you inform your doctor about the pills you take, so he can take that into account when interpreting the results. If it is possible, you can discontinue certain medication (after you have received doctor’s approval) to make sure that your blood tests are more accurate. There are many types of medications which can influence the results of blood tests, including prostate test, inflammation tests, etc. For example, nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin, ibuprofen, and naproxen can alter the results of a blood test. Other important ones include blood pressure medication, which is known as thiazide diuretics. Some of the most common medication in this category includes hydrochlorothiazide, chlorothiazide, and others. These medications tend to lower PSA levels and lead to a false diagnosis in prostate blood tests. 5-alpha reductase inhibitors also affect PSA levels. These inhibitors are represented by dutasteride and finasteride, which also decrease the PSA levels by almost 50 %. Metformin, a popular diabetes drug that is gaining anti-aging interest, can reduce B vitamin blood levels. This fact needs to be considered when testing for B-12 or other vitamins.
