Essential Biomarkers for a Healthy Pregnancy and Postpartum Recovery

Pregnancy is a time of significant physiological changes, making health monitoring crucial for the wellbeing of both the mother and the developing baby. Understanding key biomarkers can help expectant and new mothers maintain optimal health throughout pregnancy and the postpartum period. Here, we explore the importance of haemoglobin, ferritin, vitamin D, vitamin B12, folic acid, and protein levels.


Haemoglobin is a protein found in red blood cells that is critical for carrying oxygen throughout the body. During pregnancy, the volume of blood increases to support the growing fetus, often diluting haemoglobin levels. Low haemoglobin, or anaemia, can lead to fatigue, weakness, and in severe cases, complications during delivery. Monitoring haemoglobin levels helps ensure that both mother and baby are receiving enough oxygen.


Ferritin serves as an indicator of the body’s iron stores. Iron is essential during pregnancy for supporting increased blood volume, fetal growth, and brain development. Low ferritin levels can signal iron deficiency, which is linked to low birth weight. Ensuring adequate iron levels through ferritin tests can prevent anaemia and associated risks.

Vitamin D

Vitamin D is vital for bone health and immune function. It also plays a role in the development of the baby’s bones and teeth. Deficiencies in vitamin D during pregnancy have been associated with, preeclampsia, and low birth weight. Adequate vitamin D levels support maternal bone health and promote healthy development of the fetus.

Vitamin B12

Vitamin B12 is crucial for brain development and the functioning of the nervous system. It works closely with folic acid to help prevent neural tube defects and other developmental abnormalities in the fetus. Low levels of B12 during pregnancy can lead to fatigue, neurological issues, and may contribute to anaemia. Ensuring sufficient B12 intake is essential for a healthy nervous system and overall wellbeing.

Folic Acid

Folic acid is well-known for its role in preventing neural tube defects, which affect the brain and spinal cord of the developing baby. Adequate folic acid prior to conception and during early pregnancy reduces the risk of these defects significantly. It also supports the rapid growth of the placenta and foetus, making it a critical nutrient during pregnancy.

Protein Levels

Proteins are the building blocks of the body’s cells. During pregnancy, they are crucial for the growth and repair of tissues, as well as for the increase in blood volume. Monitoring protein levels can help ensure that the mother’s diet is supporting both her increased needs and those of her developing baby.


Regular monitoring of these biomarkers during pregnancy and the postpartum period can significantly impact the health outcomes of both mother and baby. At Rainbow Labs, we offer comprehensive at-home testing solutions that make it easier for expectant and new mothers to keep track of these essential health metrics. By understanding and managing these biomarkers, mothers can look forward to a healthier pregnancy and a smoother recovery postpartum.

Important Safety Information

Take any medicines called nitrates, often prescribed for chest pain, or guanylate cyclase stimulators like Adempas (riociguat) for pulmonary hypertension. Your blood pressure could drop to an unsafe level are allergic to Tadalafil or any of the ingredients in Tadalafil

Discuss your health with your doctor to ensure that you are healthy enough for sex. If you experience chest pain, dizziness, or nausea during sex, seek immediate medical help

Tadalafil can cause serious side effects. Rarely reported side effects include:

an erection that will not go away (priapism). If you have an erection that lasts more than 4 hours, get medical help right away. If it is not treated right away, priapism can permanently damage your penis

sudden vision loss in one or both eyes. Sudden vision loss in one or both eyes can be a sign of a serious eye problem called non-arteritic anterior ischemic optic neuropathy (NAION). Stop taking Tadalafil and call your healthcare provider right away if you have any sudden vision loss

sudden hearing decrease or hearing loss. Some people may also have ringing in their ears (tinnitus) or dizziness. If you have these symptoms, stop taking Tadalafil and contact a doctor right away

Before you take Tadalafil, tell your healthcare provider if you:

have or have had heart problems such as a heart attack, irregular heartbeat, angina, chest pain, narrowing of the aortic valve, or heart failure

have had heart surgery within the last 6 months

have pulmonary hypertension

have had a stroke

have low blood pressure, or high blood pressure that is not controlled

have a deformed penis shape

have had an erection that lasted for more than 4 hours

have problems with your blood cells such as sickle cell anemia, multiple myeloma, or leukemia

have retinitis pigmentosa, a rare genetic (runs in families) eye disease

have ever had severe vision loss, including an eye problem called NAION

have bleeding problems

have or have had stomach ulcers

have liver problems

have kidney problems or are having kidney dialysis have any other medical conditions

Tell your healthcare provider about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.

Tadalafil may affect the way other medicines work, and other medicines may affect the way Tadalafil works, causing side effects. Especially tell your healthcare provider if you take any of the following:

medicines called nitrates

medicines called guanylate cyclase stimulators such as Adempas (riociguat)

medicines called alpha-blockers such as Hytrin (terazosin HCl), Flomax (tamsulosin HCl), Cardura (doxazosin mesylate), Minipress (prazosin HCl), Uroxatral (alfuzosin HCl), Jalyn (dutasteride and tamsulosin HCl), or Rapaflo (silodosin). Alpha-blockers are sometimes prescribed for prostate problems or high blood pressure. In some patients, the use of Tadalafil with alpha-blockers can lead to a drop in blood pressure or to fainting medicines called HIV protease inhibitors, such as ritonavir (Norvir), indinavir sulfate (Crixivan), saquinavir (Fortovase or Invirase), or atazanavir sulfate (Reyataz)

some types of oral antifungal medicines, such as ketoconazole (Nizoral) and itraconazole (Sporanox)

some types of antibiotics, such as clarithromycin (Biaxin), telithromycin (Ketek), or erythromycin

other medicines that treat high blood pressure

other medicines or treatments for ED

Tadalafil should not be used with REVATIO or with other PAH treatments containing PDE5 inhibitors.

Tadalafil does not protect against sexually transmitted diseases, including HIV.

The most common side effects of Tadalafil: headache; flushing; upset stomach; abnormal vision, such as changes in color vision (such as having a blue color tinge) and blurred vision; stuffy or runny nose; back pain; muscle pain; nausea; dizziness; rash.
