To be honest, I didn't even know they existed.
Neither did I?
I was looking at BP monitors and below them all on the shelves was a large coeliac self test kit box. Next to it was a cholesterol test kit for little money. At left without anything but talking about the tests we decided to get one for me. So I went back for it (and got a BP monitor too, well it was two shelves up and a gadget I don't own).
Using it was easy but the 12 hours fasting wasn't! Cholesterol test was a lancet (plastic thing with a button that fires out a needle hat recedes back into plastic case afterwards, captive bolt style). You squeeze out a drop of blood (mine clotted at the pinprick before I could get a big drop to fall onto the target on the card). The blood must fill the target circle. Then time 3 minutes accurately. Too much or too little time will affect accuracy. Then you put the card into its cover and slide the card up until the dot of colour matches the range of colour bands on the card.
Then you turn it over and two windows give the cholesterol level in two different units. One of the units is in the hundreds, anything over 200 is high and they recommend more in depth testing at your GP.
I'm down as high so I'm thinking of booking a visit to the practice nurse for a cholesterol check. I'll ask for the in depth one which gives HDL & LDL levels not a single bulk level.
I've had one cholesterol check and whilst I'm it was upper levels of acceptable. I reckon it is high but not serious. I'll get it down if I need to. I also think I'm likely to be high in the good cholesterol and low in the bad one. That's what my parents tend to be so I suspect I'll be like that because we eat less high cholesterol foods than they do.
Feeling fine? Depends on how fine you think fine is. I've been slowing down on my commuting bike rides big time without the usual causes (for me it's usually good related). Overall I'm under the weather. RHR has risen too. At least I'm only mid forties, not like I'm entering the stage of life when risks start rising!
Jeez! I sound like a hypochondriac, which I'm not. I just exercise as often as possible and generally look after myself. I am always fairly consistent in activity, performance and how I feel. So a change gets noticed.
