Hs-CRP measures the level of C-reactive protein in your blood. A high-sensitivity CRP test (hs-CRP) can pinpoint smaller increases in CRP to track the progress of inflammatory diseases<span class=\"custom-citation\" data-id=\"ref-1\"><\/span>.&nbsp;<\/p>\n\n\n\n<p>Inflammation can contribute to many diseases, and it tends to go up with age with a phenomenon called inflamm-aging<span class=\"custom-citation\" data-id=\"ref-2\"><\/span>.

Insulin resistance is a condition where cells in muscles, fat, and the liver don&#8217;t respond well to insulin and can&#8217;t easily take up glucose from the blood. As a result, the pancreas makes more insulin to help glucose enter the cells<span class=\"custom-citation\" data-id=\"ref-7\"><\/span>. This can also cause elevated blood sugar, increasing overall oxidative stress and tissue glycation.&nbsp;<\/p>\n\n\n\n<p>HOMA-IR calculates insulin resistance by using a formula that incorporates fasting blood glucose and fasting insulin levels.<\/p>\n\n\n\n<p>High HOMA-IR scores indicate higher levels of insulin resistance, which can signify a higher risk for blood sugar-related conditions, potentially impacting both healthspan and lifespan. Even without diabetes and metabolic syndrome, poor blood sugar control also correlates with cognitive decline, vision problems, and skin aging<span class=\"custom-citation\" data-id=\"ref-8\"><\/span><span class=\"custom-citation\" data-id=\"ref-9\"><\/span>. Therefore, keeping your blood sugar and insulin optimized is crucial for your healthspan.&nbsp;<\/p>\n\n\n\n<p>A retrospective analysis of 5,511 non-diabetic participants in a nutrition study found that HOMA-IR was significantly correlated to all-cause mortality. There was a 64% increased risk of death in high (&gt; 2.8) HOMA-IR levels (HR = 1.64), but only in participants with a BMI less than 25.2. HOMA-IR levels above healthy (&gt;1.4) were significantly associated with cardiovascular mortality, but not cancer mortality<span class=\"custom-citation\" data-id=\"ref-10\"><\/span>.&nbsp;<\/p>\n\n\n\n<p>The test isn&#8217;t perfect\u2014results can be skewed by certain conditions or medications.

A meta-analysis of 75 studies found that each 50 mg\/dL increase in Lp(a) levels increased death from cardiovascular incidents by 30%.

Lp(a) may explain why some very fit and healthy people develop cardiovascular issues or even drop dead, especially those of European descent<span class=\"custom-citation\" data-id=\"ref-14\"><\/span>. Therefore, testing Lp(a) and being proactive if it\u2019s high can save your life. Doctors may treat it with high-dose niacin or statin, but some lifestyle factors like exercise and weight loss may also be beneficial.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">ApoB<\/h2>\n\n\n\n<p>Apolipoprotein B (ApoB) is a protein crucial for the metabolism of lipids (fats) and is a primary component of low-density lipoprotein (LDL), often referred to as &#8220;bad cholesterol.&#8221; Each LDL particle contains one ApoB molecule, so measuring ApoB levels provides an estimate of the number of LDL particles in the bloodstream<span class=\"custom-citation\" data-id=\"ref-15\"><\/span>.&nbsp;<\/p>\n\n\n\n<p>High ApoB levels are closely linked to an increased risk of cardiovascular diseases, which are major determinants of lifespan and quality of life. ApoB can be a more precise indicator of heart disease risk than traditional cholesterol tests.<\/p>\n\n\n\n<p>A retrospective analysis of 10,375 nutritional study participants discovered a U-shaped relationship between ApoB levels and all-cause mortality, with the lowest risk occurring at 108mg\/dL. You don\u2019t want too high or too low ApoB. ApoB levels had a linear relationship with cardiovascular mortality &#8211; a 25% increase in ApoB levels correlated with a 13% increase in mortality (HR = 1.13)<span class=\"custom-citation\" data-id=\"ref-16\"><\/span>.&nbsp;<\/p>\n\n\n\n<p>However, ApoB can also be influenced by genetics, diet, and other lifestyle factors.<\/p>\n\n\n\n<p>ApoB levels don&#8217;t reflect the cholesterol content within LDL particles or their size, both of which can affect disease risk.<\/p>\n\n\n\n<p>Similar to Lp(a), high ApoB levels can prompt you to make changes such as diet, lifestyle, weight management, and, if necessary, medications.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"574\" src=\"https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/12\/clairifyme_48_year_old_auburn_hair_woman_feeling_bliss_shot_o_ee2a68b6-6739-45db-b17a-28d386dfaae0_1-1-1024x574.png\" alt=\"readhead woman in the city\" class=\"wp-image-150302316266\" srcset=\"https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/12\/clairifyme_48_year_old_auburn_hair_woman_feeling_bliss_shot_o_ee2a68b6-6739-45db-b17a-28d386dfaae0_1-1-1024x574.png 1024w, https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/12\/clairifyme_48_year_old_auburn_hair_woman_feeling_bliss_shot_o_ee2a68b6-6739-45db-b17a-28d386dfaae0_1-1-768x430.png 768w, https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/12\/clairifyme_48_year_old_auburn_hair_woman_feeling_bliss_shot_o_ee2a68b6-6739-45db-b17a-28d386dfaae0_1-1.png 1456w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">DHEA-S<\/h2>\n\n\n\n<p>Dehydroepiandrosterone Sulfate (DHEA-S) is a steroid hormone produced by your adrenal glands. It&#8217;s a precursor to sex hormones like testosterone and estrogen. DHEA-S in the body peaks in early adulthood and then gradually declines with age, which is why it is sometimes viewed as a marker of aging<span class=\"custom-citation\" data-id=\"ref-17\"><\/span>.<\/p>\n\n\n\n<p>The measurement of DHEA-S levels is often used to evaluate adrenal gland function and to diagnose certain conditions related to hormone imbalance. Healthy-high levels of DHEA-S are associated with increased longevity and reduced risk for certain age-related diseases, such as osteoporosis and cardiovascular diseases.<\/p>\n\n\n\n<p>A meta-analysis of six longitudinal studies with a total of 6,744 elderly participants analyzed the association between DHEA-S levels and all-cause and cardiovascular mortality. Low DHEA-S levels (25 \u00b5g\/dL or below) were associated with a 146% and 149% increase in all-cause and cardiovascular mortality, respectively (RR = 1.46, RR = 1.49). Gender-specific analysis showed that increased risk of all-cause mortality existed only in elderly men, not women<span class=\"custom-citation\" data-id=\"ref-18\"><\/span>.&nbsp;<\/p>\n\n\n\n<p>The link between DHEA-S levels and healthspan is still not well-established. Although DHEA-S can predict aging in animals maintained on a standard diet, dietary manipulations may affect liver enzymes involved in the metabolism of steroid hormones.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">PULS (PROTEIN UNSTABLE LESION SIGNATURE)<\/h2>\n\n\n\n<p>PULS is a blood test that measures the body&#8217;s immune response to arterial injury. PULS measures injuries that lead to the formation of heart lesions which can cause heart attacks<span class=\"custom-citation\" data-id=\"ref-19\"><\/span>.&nbsp;<\/p>\n\n\n\n<p>This test measures multiple proteins produced by the body in response to damage to the inner lining of blood vessels, including those involved in inflammation, stress response, and vascular injury. These proteins include:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>hs-CRP<\/strong><\/li><li>Fibrinogen, a protein involved in blood clot formation.&nbsp;<\/li><li><strong>Hemoglobin A1c<\/strong><\/li><li>NT-proBNP (N-Terminal Pro-B-Type Natriuretic Peptide): Elevated levels indicate heart failure and are associated with increased cardiovascular risk.&nbsp;<\/li><li><strong>Homocysteine, an amino acid linked to a higher risk of coronary artery disease.<\/strong><\/li><li>Omega-3 Index, a measure of the amount of omega-3 fatty acids, which are linked to cardiovascular health.<\/li><li><strong>Lipoprotein(a)<\/strong><\/li><li>IL-16 (Interleukin-16), a cytokine that plays a role in inflammatory responses.<\/li><li><strong>sFas (Soluble Fas), a marker involved in the regulation of cell death (apoptosis).<\/strong><\/li><li>Placental Growth Factor, involved in angiogenesis (the formation of new blood vessels).<\/li><\/ul>\n\n\n\n<p>PULS test can predict acute coronary syndromes, such as heart attacks, within a five-year period. By identifying individuals at higher risk, the test provides early intervention opportunities, potentially extending healthspan by addressing and mitigating cardiovascular disease risks before they lead to a cardiac event.

High GGT levels (44 IU\/L or greater in men, 21 IU\/L or greater in women) were associated with a 33% increase in all-cause mortality (HR = 1.33), a 29% increase in cardiovascular mortality (HR = 1.29), a 38% increase in cancer (HR = 1.38), a 39% increase in respiratory disease mortality (HR = 1.39), and greater than a 500% increase in liver disease mortality (HR = 6.73)<span class=\"custom-citation\" data-id=\"ref-22\"><\/span>.&nbsp;<\/p>\n\n\n\n<p>Elevated GGT levels can prompt further investigation to identify and address underlying causes.

This is why our biological age can be different, and it\u2019s now (imperfectly) measurable.<\/p>\n\n\n\n<p>Anti-aging researchers have devised several measurements to estimate your cellular or biological age using cellular and blood tests.

The more time your cells have divided, the shorter your telomeres get and the less your tissues are able to regenerate. Therefore, shorter telomeres are associated with aging and age-related diseases<span class=\"custom-citation\" data-id=\"ref-23\"><\/span>.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Strengths:<\/strong> Telomere length is a direct biological marker and is relatively easy to measure with a blood test.<\/li><li><strong>Drawbacks:<\/strong> Telomere length varies significantly among individuals and can be influenced by:<ul><li><strong>Genetic factors<\/strong><\/li><li>Lifestyle<\/li><li><strong>Environmental exposure<\/strong><\/li><\/ul><\/li><\/ul>\n\n\n\n<p>Despite high correlation, It may not always reflect the true biological age or the health status of an individual.<\/p>\n\n\n\n<p>Unlike other age estimation methods, telomere length provides a more genetic and cellular aging perspective, focusing on chromosomal changes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Horvath&#8217;s Clock<\/h3>\n\n\n\n<p>Horvath\u2019s clock was developed by Dr. Steve Horvath in 2013. This method uses DNA methylation levels to predict biological age. The clock analyzes the methylation status of 353 specific markers in the DNA<span class=\"custom-citation\" data-id=\"ref-24\"><\/span>.&nbsp;<\/p>\n\n\n\n<p>DNA methylation involves the addition of a methyl group (one carbon atom and three hydrogen atoms) to the DNA molecule. This process is a type of epigenetic modification, meaning it affects cellular production (gene expression) without altering the underlying DNA sequence.<\/p>\n\n\n\n<p>DNA methylation plays a crucial role in controlling gene readouts. As we age, the pattern of DNA methylation in our cells changes, which can affect the expression of genes involved in various biological processes and diseases.<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Strengths:<\/strong> Horvath&#8217;s Clock is highly accurate and comprehensive, considering a wide array of genes. It has been validated across various tissues and cells.<\/li><li><strong>Drawbacks:<\/strong> The process requires sophisticated laboratory techniques and analysis. It might not fully account for lifestyle and environmental factors affecting aging.<\/li><\/ul>\n\n\n\n<p>Horvath\u2019s clock offers a more detailed and genetic-based estimation of biological age compared to simpler biomarker-based formulas.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Biomarker Based Formulas<\/h3>\n\n\n\n<p>In 2018, a cohort study developed a new aging measure, coined \u2018Phenotypic age\u2019, based on various biomarkers. The formula is as follows:<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/lh7-us.googleusercontent.com\/g3HnTa-ahsryB1xmDW9dfLxm4cI0QzPe7oHF-2J8LRASOmAROCakFqVlcxZmUNTvpmvafKHCdmtorVhhgXlIFVRUTEr2LlhPZ5q6iDDl0E_nw1Xw-fbzvJftT80mRpHQD-rRmdkx3ijgZB5aj3gJv50\" alt=\"\"\/><\/figure>\n\n\n\n<p>To estimate biological age, this method uses a combination of various blood tests readily accessible through a basic metabolic panel (BMP) and a complete blood count (CBC). These are two very common and affordable lab tests. Each biomarker contributes data related to specific aspects of health, such as inflammation, glucose metabolism, or liver function.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"574\" src=\"https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/12\/clairifyme_50_year_old_african_american_athletic_woman_jogging__f0c65a39-74bd-4489-9711-20d9e95eb56e-1-1024x574.png\" alt=\"african-american woman running \" class=\"wp-image-150302316269\" srcset=\"https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/12\/clairifyme_50_year_old_african_american_athletic_woman_jogging__f0c65a39-74bd-4489-9711-20d9e95eb56e-1-1024x574.png 1024w, https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/12\/clairifyme_50_year_old_african_american_athletic_woman_jogging__f0c65a39-74bd-4489-9711-20d9e95eb56e-1-768x430.png 768w, https:\/\/bioptimizers.com\/blog\/wp-content\/uploads\/2023\/12\/clairifyme_50_year_old_african_american_athletic_woman_jogging__f0c65a39-74bd-4489-9711-20d9e95eb56e-1.png 1456w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>Other formulas also exist, including<span class=\"custom-citation\" data-id=\"ref-25\"><\/span>:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Klemera and Doubal\u2019s method (KDM):<\/strong> The specific biomarkers can vary but often include factors like blood pressure, cholesterol levels, and other blood-based measurements.<\/li><li><strong>Strengths:<\/strong> Biomarker-based formulas can provide a broader picture of physiological aging and health risks.
