The pee-on-a-stick pregnancy test only detects the presence of hCG, and cannot measure the level of hCG in the blood. Therefore, they can be used as a screening for pregnancy, however the level of hCG can also provide information about the pregnancy. Normally, the hCG level increases and peaks at the first 14 weeks of pregnancy, and no hCG is ...
Pseudopregnancy in cats is uncommon as the queen must be bred by an infertile male to become pseudopregnant, compounded by the fact that cats are seasonal breeders. [6] The progesterone and estradiol profiles in pseudopregnancy are very different when compared to normal pregnancy. During pseudopregnancy, estradiol increases straight after ...
Following a test for blood serum thyroxine levels thyrotropin-releasing hormone can be administered to cats intravenously and after 4 hours another blood test can be taken to measure thyroxine serum levels. If the thyroxine levels have increased this indicates the cat is euthyroid but if levels remain stagnant it suggests hyperthyroidism.
Still, the blood values are approximately equal between the arterial and venous sides for most substances, with the exception of acid–base, blood gases and drugs (used in therapeutic drug monitoring (TDM) assays). [6] Arterial levels for drugs are generally higher than venous levels because of extraction while passing through tissues. [6]
When a pregnant woman is diagnosed with acute toxoplasmosis, amniocentesis can be used to determine whether the fetus has been infected or not. When a pregnant woman develops acute toxoplasmosis, the tachyzoites have approximately a 30% chance of entering the placental tissue, and from there entering and infecting the fetus. As gestational age ...
Heart disease is the most common underlying cause of arterial thromboembolism. It leads to the formation of blood clots in the heart, which leave it with the bloodstream and obstruct larger blood vessels, in cats mainly the aorta at the outlet of the two external iliac arteries. Arterial thromboembolism occurs suddenly and is very painful.
These are normal physiological adaptations that cause changes in behavior, the functioning of the heart, blood vessels, and blood, metabolism including increases in blood sugar levels, kidney function, posture, and breathing. During pregnancy numerous hormones and proteins are secreted that also have a broad range of effects.
The condition is most commonly seen in kittens with type-A blood born to mothers with type-B blood since type-B cats form very strong anti-type A antibodies. The condition is less common (and less severe) in type-B kittens born to type-A mothers. It can be prevented by blood typing the mother and kittens.
