Nurse Hatty 150 Urine Ketone Test Strips – NEW APP: Unlimited Free Scans of Any Keto Brand

These strips are one of those products that can tell you really important things at very low cost. And so I cannot recommend them enough if you're on a keto diet as these are indispensable! They are very quick to respond and provide a result for the presence of ketones in your urine. Ketones tell you that you're burning fat for fuel. The fat might be your stored fat or the fat in your diet. But regardless, some people have a very hard time switching from sugar-burning to fat-burning exclusively (most of us do both automatically, but burning sugar is easier for the body), and these strips can tell you if you've made the switch. This matters very much for those looking to burn fat off their bodies, because once you've switched to fat burning, you can lower your calories while remaining in ketosis and lose weight painlessly with little hunger. This is the beauty of the low carb diets you hear about. They are satisfying while feeling very little hunger, which allows you to cut your calories to lower levels than on carb loaded diets. In case you've not noticed, sugary and carby foods *increase* hunger... but you can nip that in the bud by eating low carb, and measure your fat burning with these strips! Studies have shown that low carb diets are more effective for losing actual fat because of these reasons. Less hunger, better adherence and satiation for the duration of the diet, and with low insulin levels, better fat burning. Anyone who thinks they can't do Atkins type diets because they get tired of high protein foods, keep in mind that the goal is not high-protein, it is moderate amounts with low carbs and high fats. Fat does not make you fat without insulin. Eat plenty of greens and vegetables and the boredom issue should not exist. Also, even if you slip out of ketosis for a while, you can always go back into it. Nothing says you can't eat carbs, just dont' do it with fats or you will deposit those more readily. Food combining diets were all the rage in the 90's as it was discovered that sugar/simple carbs and fats together are what make us fat...but I digress... I highly recommend these strips for their quick and easy readings in describing your level of ketosis, critical data for those looking to burn fat the most delicious way possible!

Frequent buyer on Auto-Ship. Works well but still difficult to read since last 3 colors appears all the same. But still better than other brands.

I’ve been using these ketone test strips for a few weeks now while following a keto diet, and they’ve been super helpful. The results are quick—usually in about 15 seconds—and the color chart is easy to read. I tested them against a blood ketone monitor and the readings were pretty consistent, which gave me confidence in the accuracy. The bottle is well-sealed and includes 150 strips, which is great value for the price. I test once or twice a day and still have plenty left. Just make sure to keep the cap tightly closed so they stay fresh. If you’re tracking ketosis or low-carb progress, these strips are a convenient and reliable option without spending a lot.

Hattie's work well and gives a good, clear reading for Keto dieters. It seems to lose potency rather quickly, though. But overall, it is a good value-based product

As I delved deeper into books about autophagy and ketones, I learned that once the body is in the state of autophagy it uses up the ketones, so less ends up in your urine. It worked for me at first, as I was a beginner starting with intermittent fasting and then getting into longer fasts. I don't regret buying these, but I would have gotten discouraged had I not done my research because shortly after my purchase, my body was using up my ketones and not dumping them into my urine any longer. Thankfully, the answers are out there. Keep looking for answers, depending on your particular need for these, I found mine by ready The Obesity Code by Dr. Jason Fung. This is an excellent product. The instructions are great and is easy to use. It gets harder and harder to read if you are starting fasting (or if you've been fasting already). Good luck!

*update 2/14/25 I’ve learned that I’m keto adapted, so these don’t really work for me anymore. They do however work fine for my husband, so it’s not a case of whether or not they work at all. He’s not on a keto diet but does eat my cooking (usually breakfast and lunch) and does his own thing for lunch or when we eat out. I ordered a blood ketones meter, that’ll be how I proceed at testing. Eat your meat, fats and low to no carbs and you too can be a loser in a good way. Bought in December of 24. Color codes on box are way different than the darker ones on the back of the test strips, so it’s hard to know which of the code colors are the best for comparison and proper readings. These test strips don’t come out of the pen size hole very easily. The Ketosis accuracy may be off as the breath meter reads so differently. Shrugging my shoulders. I’m in ketosis so I’m not gonna worry. I’ve used various brands of test strips on and off for decades, I’m not pleased with the ones I’ve used this year at all. That’s why I bought a breath meter.

These work great!

The first strip I got had an opening that was so hard to get through, I eventually used scissors. The pen and my finger wouldn't go through no matter how hard I pushed. I finally got through but the hole was a little bigger than pen sized. After days of using them, it looked like there was a little bit of pink but it was hard to tell. It was so hard to tell between negative and a trace even though I was having 20 and under carbs a day. I decided this were defective and got new ones. The replacement had a completely different top!!! I was expecting an extremely difficult foil seal so I pushed hard with my finger. There was no seal just foil! My finger immediately went through making a very big hole. Why was there two different foil seals!!! I decided to store these strips in my closet where it was dark, cool, and dry. The first strip worked, all the others did not. Every single strip stayed exactly the same color. Didn't even change to show negative. I know I was in ketosis. I have been intermittent fasting and eating less than 20 carbs a day, sometimes only 8-10. I will attempt to buy a different brand. These obviously don't work. Maybe if they had the same foil seal, I would've been able to make that small hole, but they didn't. I still can't imagine a finger sized hole seriously making the entire batch bad. I still quickly removed the strip and immediately replaced the cap.

I'm using these only when I am not using a ketone monitor (medical device) to measure my ketones. I.e. in between blood tests. What I recommend is that you use a ketone monitor if you can afford one, to get your 'right now' ketosis status, but using a ketone strip will help you just keep a track of the ketones *trend* in your body. They are not showing you what you have in the body, but the ketones you have LOST in urine, that have not been taken up for use as energy by the body. However, if you're losing them, at least you know they were there in the first place, which is a good thing. The ketone monitor (I use the On Call system) measures the 'right now' level of blood ketones. The ketone strip--that you pee on--measures the EXCRETION of ketones from your body. So, for example, if yesterday I did a blood test using the monitor and found my blood ketones were getting a bit low, I'd use a keto strip the next day to see if I excreted a lot. If I did, chances are I now don't have a high enough ketone reading so I might do a blood test to be sure. Or, I could just say, well, my blood ketones were lowish yesterday and I have lost a few, so let's take in more healthy fats and zero carbs, medium protein, etc, to push back into ketosis. Excreting a lot of ketones and showing a high level on even a keto strip could, of course, mean I have a very high blood level of ketones. But if I am following my trends, I will know which scenario applies. I have never encouraged a blood level above 2.0 mmol so I know that if I excrete too many, I am probably close to losing ketosis unless I modify the diet to raise the level. So, the keto strips are a very useful and cheap way to monitor which direction my ketones are moving--up or down. It's a case of wising up about myself and seeing what works; I am now at a stage where just knowing what my level was yesterday, and then peeing on a keto strip, will often give me within .1 mmol of what my blood test will show today. In other words, I am watching the trend and can deduct from that, how my body ketosis is. There are many days on which I do not have to use up a test strip and a lancet (needle) for my device simply by using the ketone strips as my interim trend monitor. It is important to use them that way--to measure the trend of ketones excreted--to a) know that you are likely still in ketosis and b) to know whether you're excreting and therefore wasting too many. Many people think a nice dark colour on a keto strip is good. It isn't really. a) you don't want high ketones in the body to a point where the pee strip turns too dark, as high ketones are dangerous (ketoacidosis). And b) as the pee strip measures ketones LOST in urine, it shows you're just wasting a percentage of your fuel. Because the excretion into the urine is more a reflection of what happened the day prior, (whereas blood tests show it as it is now) then I also don't read too much into a strip reading within the urine method. It shows a trend, not an actual. Here are two examples: Day 6. Blood ketone reading, 1.9 mmol. This was up on the previous day's blood test. Keto strip reading--showed 'moderate' which meant I had excreted many of these ketones. I either had to up my level of exercise to burn more fat and use up the extra ketones, or I needed to lower my caloric fat to lower my ketones next day. There was also a chance my body was producing more ketones in response to, say, fasting, but my personal pattern of eating and how these patterns show in the ketones, would usually indicate that the levels will drop soon if I have seen a ketone spike up around 1.6 and higher. Day 8: Blood ketone reading, 1.2 mmol. This was down on the previous day's blood test. Keto strip reading--showed 'light/trace' which meant I had excreted many of these ketones again. I had to increase my intake of healthy fats to increase my ketones slightly, because I foresaw that if I didn't, the ketones level in the blood could fall to below 0.5 by the next day, and I could end up losing the state of ketosis. Day 12 I restricted my diet too much and my blood level fell to 0.8 mmol. I was able to increase healthy fats intake, and use a keto strip to pee on, to know that I was back in the 'trace' excretion level next day. This told me that if I did bloods, I'd be okay. I did take bloods, just to test my hypotheses about the trends, and my blood was showing 1.3 mmol again, so the strips are always an indicator of an upward or downward trend. You can, of course, just pee on one daily and not spend on a blood monitor, if all you want to know is that you're in ketosis. However, if you start to get very low pee readings on the urine strip, be careful, as you could easily lose ketosis by the next day. Always use these as indicators. The Nurse Hatty strips seem extremely reliable; I test them occasionally against Ketonix brand, and the colours are always the same.

I love having the comparison colours on the strip itself. It makes reading the levels so easy. Definitely was a good choice.

Habe mir die Strips gekauft, da sie die einfachste und günstigste Methode sind, bei einer Low Carb Ernährung die Ketose zu überwachen. Die Strips sind etwa 10 cm lang und aus Kunststoff, an einem Ende befindet sich der Reaktionsstreifen. Einfach draufpinkeln, 40 Sekunden warten und Färbung mit den Farbquadraten auf der Dose vergleichen. Das geht morgens beim ersten Toilettengang ganz einfach nebenbei. Anfangs dachte ich, die Strips funktionieren vielleicht nicht, da sie wochenlang immer die gleiche Farbe (=Dosis an Ketonen) angezeigt haben, aber nach einem Urlaub lagen die Ketone ein paar Tage deutlich niedriger. Auf der Dose steht übrigens, dass 50 gratis Teststreifen dabei liegen, nicht nur 25, aber ich habe die jetzt ehrlich gesagt nicht abgezählt... Ich würde sie wieder kaufen.

I have only just started on my keto diet but I found these sticks invaluable, you can see how close you are to getting into ketosis, no guessing just pee on the stick in 40 seconds you’ll know.

Hab schon zweite mal bestellt , hilft sehr gut bei Ketose messen , Misst nicht anders wie die teurere Test Streifen ( schon ausprobiert ) Preis Leistung super, kann ich nur empfehlen
