What is HOMA IR?

HOMA IR is a calculation used to estimate insulin resistance. It utilizes the fasting glucose and insulin concentrations in the blood. Insulin resistance indicates how well your body responds to insulin, the hormone that regulates your blood sugar level.

Why should you test HOMA IR?

Testing HOMA IR is useful for detecting early signs of insulin resistance. This is especially relevant for people with an increased risk of developing type 2 diabetes, metabolic syndrome, or heart diseases. It can also be beneficial for those who want to accurately monitor their health and take preventive measures.

What does it indicate?

A HOMA IR score provides an indication of the body's efficiency in using insulin to remove glucose from the blood. It helps in identifying insulin resistance, a condition where higher levels of insulin are required to transport glucose to the cells.

What does a high HOMA IR level mean?

A high HOMA IR level indicates insulin resistance, meaning your body has more difficulty removing glucose from your blood, despite the presence of insulin. This can be a precursor to type 2 diabetes and is associated with other metabolic disorders.

What does a low HOMA IR level mean?

A low HOMA IR level suggests good insulin sensitivity, meaning your body can efficiently remove glucose from your blood and use it for energy. This is generally considered an indicator of good metabolic health.

“Hele fijne en snelle service”

Hele fijne en snelle service! Ik contacteerde ze ‘s nachts omdat ik zsm moest bloedprikken, ik kon die ochtend nog terecht en heb dezelfde dag mijn uitslag binnengekregen. Echt top!!

Madina ShinwariVerified

“Bloedcheckup levert”

Waar ziekenhuizen moeilijk doen om checkup te doen , komt Bloedcheckup naar boven drijven als vertrouwde partner op gebied van gezondheid. Ik ben uiterst tevreden met bloed checkup

JoaquinVerified

“Klantenservice was erg behulpzaam in…”

Klantenservice was erg behulpzaam in het beantwoorden van mijn vragen. Ik had ook een extra setje buizen nodig als back-up en dat was geen probleem. Ik had een groot test panel besteld, maar de resultaten waren binnen 1 week binnen. Rapport zag er netjes uit.

ErnstVerified

“Snelle en goede service”

Je hebt de spullen snel in huis en het is duidelijk wat je daarna moet doen. Ook de uitslag heb je snel in huis, ik dezelfde avond al de eerste uitslagen. Bij een bepaling ging het fout, niet eens door het bedrijf maar door het bloedafname punt en die bepaling kreeg ik gewoon vergoed, ook het geld terug stond erg snel op mijn rekening. Vragen worden ook snel beantwoord dus al met al een positieve ervaring bij Bloedcheckup.nl

“Fijn bedrijf met geweldig veel opties…”

Fijn bedrijf met geweldig veel opties om zelfstandig je gezondheid in het oog te houden, als sporter een must want de dokters hebben toch geen verstand van wat relevant en anders is voor sport. Ook zeer tevreden over Stijn zelf! Aangename kerel en goed bereikbaar voor vragen en hulp tijdens bestellen :D

MyronVerified

“My experience was very positive”

My experience was very positive. I needed to pass several very specific tests. They provide 24/7 customer support. They were friendly and prompt.

Olesia TaldykinaVerified

“Top!”

Snelle en makkelijke afhandeling. Duidelijke instructies en binnen anderhalve dag al resultaat binnen. Top service!

ZerinaVerified

“Amazing service!”

Received a packet with everything needed, went to a walk in clinic (Amsterdam DC Clinic) where my blood was drawn and I was out the door within 5 minutes, and then after posting the samples, received results 2 days later. Results were easy to understand as well. Amazing service, would highly recommend!

Limited evidence in mainstream medicine

The scientific support for this test within mainstream Dutch healthcare is limited. The test is not included in NHG/FMS standard guidelines.

Rationale for this test

Microbioomanalyse van de darm is een onderzoekstechniek die in ontwikkeling is binnen de wetenschap. Er is wetenschappelijk bewijs dat darmbacteriën een rol spelen bij gezondheid en ziekte, maar de klinische betekenis van microbioomtesten voor individuele diagnostiek of behandeling is nog beperkt. Deze test is niet opgenomen in Nederlandse zorgrichtlijnen (NHG/FMS) als standaard-diagnosticum. De interpretatie van resultaten en de vertaling naar concrete gezondheidsadviezen zijn nog onvoldoende gestandaardiseerd voor routinematig gebruik.
