Hemorrhoids maybe a taboo to talk, but they are serious menace (unexpected soiling, interfere with colorectal cancer screening). Known in antiquity to Egyptians, Babylonians, Greeks & in Old Testament, Hippocrates wrote a whole treatise "On Hemorrhoids". rxhometest.com/resource/gi-h…

Colorectal Cancer Screening - what to know about blood in stool? Despite low awareness blood is stool, especially from hemorrhoids is very common (up to 1 in 3 people). A FIT test checks human globin from colon to detect polyps & early signs of cancer. rxhometest.com/resource/gi-h…

Can Hair be Used for Health Testing? Hair can be an easy method for monitoring metal toxicity, especially for Mercury (from seafood), Arsenic, Cadmium & Lead. It's often used for metals & nutrients ingested through food & water (not airborne exposure). rxhometest.com/product/hair-…

H. pylori is known to cause peptic ulcers, gastritis. Testing options to confirm symptoms: 1. Antigen test - checks bacterial proteins 2. PCR test - checks DNA 3. Antibody test - antibodies from infection 4. Breath test - urease enzyme made by bacteria. rxhometest.com/resource/h-py…
29
H. pylori Antigen vs PCR Tests Guidelines from the American College of Gastroenterology (ACG) say antigen tests can have sensitivity of 88-95%, specificity of 92-97%. PCR tests generally have higher sensitivity, about 93-98% & specificity over 98%. rxhometest.com/resource/h-py…

H. pylori Antigen vs DNA Test: An antigen test checks bacteria proteins & is useful in confirming a successful treatment. A DNA or PCR test checks DNA of the bacteria. It can help plan a treatment (with virulence factors & antibiotic resistance genes). rxhometest.com/product/h-pyl…

Lp(a) vs LPA: Lipoprotein-little-a is lipoprotein particle in your blood (similar to cholesterol). LPA is a gene. Both are markers of heart health & related to cholesterol & lipids. LPA as the genetic instruction to help make Lp(a) blood particle. rxhometest.com/resource/Lpa-…

👉Heterogeneity in Lipoprotein(a) Profile Changes Across the Menopausal Transition ☝️New data challenge the concept of Lp(a) as a truly “once-in-a-lifetime” measurement—particularly across menopause. 1️⃣ In 4,562 women from the UK Biobank, overall changes in Lp(a) over ~4 years were modest. 2️⃣ Among women with baseline Lp(a) 75–125 nmol/L, those transitioning through menopause showed a median increase of 34.9 nmol/L—~4× greater than women remaining pre- or postmenopausal. 3️⃣ 56.4% of these women crossed the clinically relevant ≥125 nmol/L threshold after menopause, versus ~29% in the comparison groups. 4️⃣ After adjustment for age and baseline Lp(a), menopausal transition was associated with a 2.27-fold higher risk of crossing that threshold. ☝️Take-home message: Lp(a) is largely genetically determined, but not necessarily biologically static. Repeat measurement after menopause may be particularly relevant when premenopausal Lp(a) is in the intermediate range 🔗🔓 academic.oup.com/eurjpc/adva… @society_eas

Lp(a) is LDL-like particle, elevated for 1-in-5 people. Lp(a) is genetically inherited & should be tested at least once in lifetime (2026 Guidelines). High levels cause arterial plaque, inflame vessel walls, promote clotting & aortic valve damage. rxhometest.com/resource/Lpa-…

Lp(a) vs LPA - What's Difference & What To Test For? - Lipoprotein(a) or Lp(a) is part of a blood test - mostly INHERITED - should be tested **at least once** in lifetime (2026 Guidelines) - LPA is a gene that codes for APOA; modifies LDL to make Lp(a) rxhometest.com/product/chole…

Between 2003–2023, sub-Saharan Africa had the greatest declines in HIV incidence (64.3%) & mortality (74.6%), while Central Europe, Eastern Europe, & Central Asia recorded the highest increases in incidence rates (232.1%) & mortality rates (37.8%). ms.spr.ly/6016aTZBw

A US citizen born in 2024 is expected to live up to the age of 79 years. Women will live even longer (81.4 years), while men have about 5 years shorter lifespan (76.5 years). Asian American women have the highest life expectancy at 87.7 years. rxhometest.com/blog/rxhomete…

The "family tree" of hormones. Everything begins with cholesterol: most people think of Cholesterol only in terms of heart disease. But biologically it is the raw material for all steroid hormones: DHEA, Testosterone, Cortisol, Progesterone, Estrogen. rxhometest.com/product/endos…

The cortisol awakening response (CAR) is a sharp rise in cortisol levels after waking up. It is distinct from the 24-hour diurnal rhythm. In a normal person without significant stress, cortisol is highest at 30-60 mins after waking up. rxhometest.com/product/endos… #stress #cortisol

Since PSA Screening was first introduced in 1980s, prostate cancer rates in US have come down to about 1 in 20 men. Rates have risen in men under the age of 50y, but fallen significantly for those over 80y. PSA screening tests are now widely available: rxhometest.com/product/psa-p…

Despite our craze for protein, research suggests LOW protein diets actually increase life span & improve many health markers. In general, calorie restriction has been consistently proven to increase lifespan (since 1935). Learn more: doi.org/10.1016/j.cpblue.202… #rxhometest

Iron deficiency is a common nutritional deficiency worldwide. In US, 1 in 20 men & 1 in 7 women have iron deficiency (CDC); child bearing age highest risk (17%). 1 mg of iron is lost daily through stool, skin, mucous & GI (women lose 0.3-0.5 mg more). rxhometest.com/product/iron-…

Higher pain resiliency, emotional stability, memory & addiction - all are controlled by brain's prefrontal cortex. One of the controlling knobs is COMT, as it affects neurotransmitter (e.g., dopamine) levels. COMT gene variants are key to our behavior. rxhometest.com/article/comt-…
