The 5 blood values most frequently cited for a long and healthy life are HbA1c, ApoB, hs-CRP, Lp(a), and Vitamin D. Together, they show how the body handles sugar, fats, inflammation, hereditary risk, and an important vitamin.
Read first
A blood test is a snapshot and not a diagnosis. The following values are general reference points. A physician evaluates them in the context of age, family history, and symptoms. In Germany, some of these tests are often out-of-pocket services, so it is worth asking the practice before booking an appointment.
1. HbA1c: the sugar memory
A single blood sugar measurement only shows a moment in time. HbA1c shows the average blood sugar of the last two to three months. This means the value can hardly be manipulated by a good breakfast the day before.
Reference values: Below 5.7 percent is considered normal. 5.7 to 6.4 percent is the prediabetes range. The diabetes range begins at 6.5 percent.
What influences it: Dietary fiber, regular exercise, a walk after eating, sufficient sleep, and a healthy weight.
2. ApoB: the particle count
Most people are familiar with LDL cholesterol. ApoB goes a step further. Every particle that can lodge in an artery wall carries exactly one ApoB molecule, which is why this value counts the particles. You can think of LDL as the amount of cargo and ApoB as the number of delivery trucks.
Large studies and genetic research show that these particles are a direct cause of clogged arteries. Target values depend on personal risk and are determined by a physician.
What influences it: Replacing butter with olive oil, more fiber and beans, a healthy weight, and medication if advised by a physician.
3. hs-CRP: the inflammation signal
hs-CRP is a protein produced by the liver when there is inflammation in the body. The high-sensitivity test also detects small, persistent levels that you cannot feel yourself.
In a study of nearly 28,000 women, hs-CRP predicted heart attacks and strokes better than LDL cholesterol.
Reference values: Below 1 mg/L means low risk. 1 to 3 mg/L is average. Above 3 mg/L is high. A cold or infection can increase the value for weeks, so the test should be taken when healthy.
What influences it: Exercise, a healthy weight, not smoking, and sleep. A review article found that poor sleep is associated with higher inflammatory markers.
4. Lp(a): the value set at birth
Lp(a) is a fat particle that is largely determined by genes. About one in five people has an elevated level, and most do not know about it. Lifestyle changes hardly affect it.
The good news: As a rule, it only needs to be measured once in a lifetime. Those who know they have a high level can work with a physician to keep all other risk factors as low as possible years earlier than usual.
5. Vitamin D: the autumn value
Vitamin D is a hormone-like substance that the skin produces in sunlight. It is needed for bones and the immune system. A nationwide health study found that more than half of adults in Germany had levels below the recommended 50 nmol/L.
Reference values: Below 30 nmol/L is considered a deficiency. From 50 nmol/L, the value is considered sufficient for most people.
What influences it: Sunlight on uncovered skin from spring to early autumn and fatty fish. In the dark months, many people need medical advice on whether a supplement is useful. Whether Vitamin D provides protection beyond bone health is still being debated.
Where LongevityLife. comes into play
Blood values are the report card of daily habits. Sleep is one of the few habits that touches several of them at once, which is why the evening routine is so important. At LongevityLife, nasal strips are part of this routine because they allow more air to flow through the nose at night. They do not change any of these values. They simply support a better night's rest.
The bottom line
HbA1c, ApoB, hs-CRP, Lp(a), and Vitamin D provide a clear picture of what is happening under the surface. An annual check-up costs little and can make problems visible years before the first symptoms appear.
